No broken windows if we can help it. + +# The HyperBEAM Style Guide. + +**Rule one of style guide club:** _We do not talk about style guide club._ + +We are here to build a fully decentralized alternative to cyberspace as it +is currently constructed. We are not interested in long conversations about +where to put commas or spaces. + +**Rule two of style guide club:** _Blend in._ + +Rule one does not imply that we do not care about the quality of the codebase. +Far from it: We know that we will be maintaining this code for decades to come. +It is important that we are all aligned on style and patterns, but less important +what those styles and patterns actually are. Having `length(Contributors)` +styles adds overhead to understanding the codebase, which over time hides bugs +and reduces maintainability, but each stylistic choice is largely an opinion +that -- despite strong feelings -- lacks criticality. Hence, rule two: +Only write and merge code that actually _blends in_. + +Write your code as if you were the author of all of the existing code. If all +of the other code is written in a certain style, then copy it. If the style +of the code in your PR would not _blend in_, then its style is objectively +in violation of `style guide club`'s rules. + +In the event of disagreement, a simple rule should guide our decisions: What +does the majority of the LoC in the codebase already do? Do that. Then get +back to hacking. + +If you don't like something about the style, simply contribute. If others +disagree strongly, the existing style will be kept. If your contributions are +seen by others as reasonable and inline with the canon, then it will gradually +become adopted as the standard in the codebase. + +**This concludes the rules of style guide club.** + +Remember: Cypherpunks write code! + +# A Rough Guide to the HyperBEAM `canon` + +You should pick up and continue the style of the codebase as you learn how it +works. There is no real substitute for paying attention. There are, however, a +few basic rules that are widely established and represent the core `canon` of the +codebase. As of time of {{`git blame`}}, there is highest consensus around the +following: + +- Always use `-` over `_` in binary key names. + - Why: In general we try to follow the HTTP semantics RFC 9110, so all keys + should be HTTP-Header-Case. This is the style that has been used for Arweave + data protocols since inception, so to avoid confusion we maintain it in + HyperBEAM. + - Nuances: + - One weirdness we inherit from HTTP-land is that headers are actually + case-insensitive, despite the use of capitals in header descriptions, + over-the-wire they are lower-case in HTTP/2+. AO-Core shoots for the + same semantics for consistency. + - In device key resolutions that have multiple words (for example: + `i_like(Base, Req, Opts) -> {ok, <<"Turtles!">>}.`) you may be tempted + to call `~device@1.0/i_like`. Don't. Instead call `/i-like`. + `hb_ao_device` will normalize the keys and match for you. + - `hb_opts` uses all atoms for its message keys. This is a mistake. It + is nice to be able to lookup keys via atoms (normalizing as above) and + we should maintain this, but under the surface the keys should be + normal-form binaries. To avoid issues when this is translated, perform + `Opts` lookups with only atoms, or use binaries of normal-form if you + must. +- Try to keep lines to around 80 characters-ish. This is not a strict rule because + sometimes an 81-85 character line would be very ugly and harder to follow if split. + Use your judgement. + - Why: Our objective is to keep the code readable. Monster lines, and machine-enforced + strict styles, both butcher this. Human/LLM judgement can help here. +- Add a `%%% @doc` moduledoc to each new module you write, and comment every + function you write with a `%% @doc Description` above it. Inline comments are + prepended with a single `%`. + - Why: This helps humans and LLMs grok your code in the future. It also surfaces + useful information in tooltips etc upstream. + - Nuance: I do not know why the Erlang style uses `%%%` for moduledocs, `%%` for + functions, and `%` for inline comments, but it does. This can help with parsability + for some tooling and the effort-cost is minimal, so we use it. +- Avoid 'waterfalls'-style statements, instead keeping every set of statements + nested such that the start and end of the block are indented inline with each + other. + - Why: This uses slightly more lines, but makes deeply nested code much more + readable and comprehensible. + - Examples: +```erlang + BadForm = lists:map( + fun(X) -> + X * lists:sum(lists:fold( + fun(Y, Acc) -> + Y * Acc + end, + [1,2,3] + )) + end + ), + GoodForm = lists:map( + fun(X) -> + X * + lists:sum( + lists:fold( + fun(Y, Acc) -> + Y * Acc + end, + [1,2,3] + ) + ) + end + ) +``` +There are a few areas where there is no consensus on patterns or style yet: +- Expressing docs in the info/[0,1] call of devices. There are a few different + styles in different devices in the codebase -- if you want to add info response + 'inline' docs try to pick one that already exists and see what works/doesn't. + We will need to unify them at some point. +- `maybe ... end` vs nested `case` expressions. `maybe` seems useful and preferable + in at least some cases, but bubbling the right error -- rather than just an error -- + the caller can sometimes be difficult due to the `else` pattern matching. + Experimentation with patterns here would be good. \ No newline at end of file diff --git a/Dockerfile b/Dockerfile index a78f0137b..593425060 100644 --- a/Dockerfile +++ b/Dockerfile @@ -1,4 +1,4 @@ -FROM --platform=linux/amd64 ubuntu:22.04 +FROM ubuntu:22.04 AS builder RUN apt-get update && apt-get install -y \ build-essential \ @@ -7,7 +7,9 @@ RUN apt-get update && apt-get install -y \ pkg-config \ ncurses-dev \ libssl-dev \ - sudo + sudo \ + curl \ + ca-certificates RUN git clone https://github.com/erlang/otp.git && \ cd otp && \ @@ -21,15 +23,347 @@ RUN git clone https://github.com/erlang/rebar3.git && \ ./bootstrap && \ sudo mv rebar3 /usr/local/bin/ -RUN git clone https://github.com/rust-lang/rust.git && \ - cd rust && \ - ./configure && \ - make && \ - sudo make install +# install node 22 (used by genesis_wasm profile) +RUN curl -fsSL https://deb.nodesource.com/setup_22.x | bash - && \ + apt-get install -y nodejs && \ + node --version + +RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y +ENV PATH="/root/.cargo/bin:${PATH}" + +WORKDIR /opt + +COPY . . + +# compile the project with provided profiles +RUN rebar3 clean && rebar3 get-deps && rebar3 as genesis_wasm release + +FROM ubuntu:22.04 AS runner + +WORKDIR /opt + +# Install Node 22 dependencies +RUN apt-get update && apt-get install -y \ + ca-certificates \ + curl \ + gnupg + +# node 22 is still needed for genesis_wasm profile +RUN curl -fsSL https://deb.nodesource.com/setup_22.x | bash - && \ + apt-get install -y nodejs && \ + node --version + +# copy the build artifacts from the builder stage +COPY --from=builder /opt/_build/ /opt/_build/ + +# copy the wallet file +COPY wallets/wallet1.json /opt/_build/genesis_wasm/rel/hb/hyperbeam-key.json + +# Apply genesis-wasm fixes: +# Fix 1: parseInt string concatenation bug (from = '438779' + 1 = '4387791' instead of 438780) +RUN sed -i 's/if (!isColdStart) from = from + 1/if (!isColdStart) from = parseInt(`${from}`) + 1/' \ + /opt/_build/genesis_wasm/rel/hb/genesis-wasm-server/src/effects/hb/index.js +# Fix 2: Allow genesis-wasm to fetch messages from HyperBEAM scheduler when body is insufficient +# (needed after restart to catch up from checkpoint without failing) +RUN sed -i "/if (!dryRun) throw new Error('Body is not valid: would attempt to fetch from scheduler in loadMessages')/d" \ + /opt/_build/genesis_wasm/rel/hb/genesis-wasm-server/src/effects/hb/index.js +# Fix 3: Allow loadMessageMeta to fetch from scheduler when body is missing/invalid +# (needed for dryrun with ?to= pinning; previously always threw) +RUN node -e " + const fs = require('fs'); + const file = '/opt/_build/genesis_wasm/rel/hb/genesis-wasm-server/src/effects/hb/index.js'; + let c = fs.readFileSync(file, 'utf8'); + c = c.replace( + \" throw new Error('Body is not valid: would attempt to fetch from scheduler in loadMessageMeta')\", + ' return fetch(\`\${suUrl}/~scheduler@1.0/schedule?\${toParams({ processId, from: messageUid, to: messageUid, pageSize: 1 }).toString()}\`).then(okRes)' + ); + fs.writeFileSync(file, c); +" + +# Fix 4: Pass the correct 'before' target to findFileCheckpointBefore and +# findRecordCheckpointBefore in findLatestProcessMemory.

The remainder of this module document +--- provides a breif overview of its design, and focuses on its implementation +--- details. +--- +--- ## Design and Implementation +--- +--- If running as a `root' token (indicated by the absence of a `token' field), +--- the `balance' field should be initialized to a table of balances for the +--- token during spawning. The `ledgers' field holds the state of a sub-ledger's +--- own balances with other ledgers. This field is always initialized to a message +--- of zero balances during the evaluation of the first assignment of the process. +--- When the token receives a `credit-notice' message, it will interpret it as a +--- deposit from the sending ledger and update its record of its own balance with +--- the sending ledger. +--- +--- Atop the standard token transfer messages, the sub-ledger API allows for +--- `transfer' messages to specify a `route' field, which is a list of ledger +--- IDs that the transfer should be routed through in order to reach a +--- recipient on a different ledger. At each `hop' in the route, the recipient +--- ledger validates whether it trusts the sending ledger and whether it knows +--- how to route to the next hop. If the recipient ledger does not trust the +--- sending ledger, it will terminate the route with a `route-termination' +--- message. If the recipient ledger knows how to route to the next hop, it +--- will create a new `transfer' message to the next hop, with the first +--- ledger from the route removed and the remainder of the route and recipient +--- and quantity to transfer forwarded along with the message. +--- +--- There are three security checks performed on incoming messages, above the +--- standard balance transfer checks: +--- +--- 1. Assignments are evaluated against the `assess/assignment' message, if +--- present. If not, the assignment is evaluated against the process's own +--- scheduler address. +--- +--- 2. If the message does not originate from an end-user (indicated by the +--- presence of a `from-process' field), the message is evaluated against +--- the `assess/request' message, if present. If not, the message is +--- evaluated against the `authority' field. The `authority' field may +--- contain a list of addresses or messages that are considered to be +--- authorities. +--- +--- 3. `credit-notice' messages that do not originate from a sub-ledger's +--- `token' are evaluated for parity of source code with the receiving +--- ledger.

The script is built for operation with the HyperBEAM +`~lua@5.3a` and `~process@1.0` devices. + +In addition to implementing the core AO token ledger API, `hyper-ledger.lua` also +implements a `sub-ledger` standard, which allows for the creation of networks +of ledgers that are may each hold fragments of the total supply of a given token. +Each ledger may execute in paralell fully asynchronously, while ownership in their +tokens can be viewed as fungible. The fungibility of tokens across these ledgers +is created as a result of their transitively enforced security properties -- each +ledger must be a precise copy of every other ledger in the network -- as well as +the transferrability of balances from one ledger to another. Ledgers that have +`register`ed with one another are able to transfer tokens directly. A multi-hop +routing option is also available for situations in which it may be desirable to +utilize pre-existing peer relationships instead. + +This document provides a terse overview of the mechanics of this standard, and +the specifics of its implementation in `scripts/token.lua`. + +## 1. Entities and State + +### 1.1 Entities +- **User Account**: Identified by wallet address, may own tokens in `ledgers`. +- **Ledger Process**: An AO process implementing this token script. +- **Root Ledger**: The base token ledger process, from which supply scarcity is + derived. Root ledgers are differentiated from `sub-ledger`s by the absence of + a `token` field. +- **Sub-Ledger**: An independent ledger that that may own tokens in the root + ledger, holding them on behalf of users and other ledgers in the network. + All sub-ledgers must have a `token' field in their process definition, which + contains the signed process ID of the root ledger. + +### 1.2 State + +Each ledger maintain the following fields: + +- `balance`: A message containing a map of user addresses to token balances. +- `ledgers`: A message containing a map of peer-ledgers and the local ledger's + balance in each. +- `token`: (Optional) The signed process ID of the root ledger. + +Additionally, ledgers (root or sub-ledger) may maintain any other metadata fields +as needed in their process definition messages. Both metadata and necessary +fields are available via the AO-Core HTTP API. + +## 2. Message Paths and Actions + +All instances of this script support calling the following functions, as either +the `path` or `action` of scheduled messages upon them: + +- **Register**: Attempt to establish a trust relationship between ledger peers. +- **Register-Remote**: User-initiated request for the recipient ledger to + register with a specific remote peer. After registration, the user may transfer + tokens from their own account on the registrant ledger, to the remote ledger + that they specified. +- **Transfer**: Move tokens between accounts (with optional routing). +- **Credit-Notice**: Notification sent by a ledger to a recipient of credit upon + a successful transfer. +- **Debit-Notice**: A notification granted by a ledger to a sender of tokens, + upon successful transfer. +- **Credit-Notice-Rejection**: A notice sent by a ledger to the sender of tokens, + if the ledger is unable to accept the transfer (crediting its own account). + This action occurs when the recipient ledger is unable to validate the sender + as a valid peer, or when the recipient ledger is unable to validate the + quantity of tokens being transferred. Upon receipt, a process will likely + wish to reverse the transfer locally. +- **Route-Termination**: Notice, dispatched to a sender of tokens, if the + ledger is unable to forward the transfer to the next hop in the stated route. + Upon receipt, senders will typically wish to send a new transfer request to + the ledger with a different route to reach their recipient. If all other + routes are exhausted, the sender may transfer the tokens to the root ledger. + +## 3. Core Process Flows + +### 3.1 Ledger Registration and Trust Negotiation. + +1. Ledger A sends `Register` to Ledger B. The `push-device` that delivers this + message to the recipient (for example, `push@1.0`) must add the + `from-process-uncommitted` field to the message, containing the hash of the + sending process. +2. Ledger B validates: + - The admissibility of the assignment (its `scheduler` commitment), + - Whether it trusts the computation commitments upon the message, and + - Whether the message is from a process that is executing precisely the same + code as the recipient, as signified by the `from-process-uncommitted` field. +3. Ledger B adds Ledger A to its list of trusted peers, if it is not already + present, and sends a reciprocal `Register` message to the sending ledger. +4. Ledger A validates and adds Ledger B using the same mechanism, then adds it + to its list of trusted peers. +5. **Result**: Bidirectional trust relationship, and the ability to transfer + tokens directly between the two ledgers. + +### 3.2 Direct Cross-Process Transfer + +**Objective**: `Alice` wants to send tokens to `Bob`, who is on Ledger B. There +is an established peer relationship between Ledger A and Ledger B. + +1. `Alice`, with tokens resident on Ledger A, initiates transfer to `Bob`, who + would like to receive tokens on Ledger B. Ledger B already has an established + trust relationship and sufficient balance for `Alice` to send tokens to `Bob`. +2. Ledger A validates request, checks their balance for `Alice`, and debits the + sender's account. +3. Ledger A sends a `Transfer` message to Ledger B. +4. Ledger B validates sender ledger, decrements sender's balance, and credits the + recipient's balance. + +### 3.3 Multi-Hop Transfer + +**Objective**: `Alice` wants to send tokens to `Bob`, who is on Ledger N, but +there is no peer relationship between Ledger A and Ledger N. + +1. `Alice` initiates a transfer on Ledger A, with a multi-hop route + (`route=[Lโ‚, Lโ‚‚, ..., Lโ‚™]`) to reach `Bob` on Ledger N. +2. As with S`3.2`, Ledger A validates request, checks their balance for `Alice`, + and debits the sender's account. +3. Each intermediate ledger in the route validates the balance of the sending + ledger, and debits their account. Each ledger also removes themselves from the + list of hops remaining in the `route` parameter of the request, and forwards + it onwards to the next hop. +4. Final ledger in the route validates the balance of the sending ledger, and + credits the `Bob`'s account. + +### 3.4 Transfer with Peer Registration + +**Objective**: `Alice` wants to send tokens to `Bob`, who is on Ledger B. There +is no peer relationship between Ledger A and Ledger B, but `Alice` would rather +establish one than route the transfer through a potentially longer multi-hop +route. + +1. `Alice` sends a `Register-Remote` message to Ledger B, with a `peer` parameter + of Ledger A's signed process ID. +2. Ledger B validates the request, and adds Ledger A to its list of trusted peers. +3. `Alice` sends a `Transfer` message to Ledger B. +4. Ledger A and B validate the transfer request, as in `3.2`. + +## 4. Intended Security Properties + +1. **Code Integrity**: Each new peer relationship validates that each other + peer is executing precisely the same code as it is. Subsequently, the + security properties of the original ledger are transitively applied to all + new ledgers in the network. +2. **Conservation of Tokens**: As each peer may trust each other peer to monitor + balances as they would, the network as a whole maintains the conservation + of the total supply of tokens. +3. **Trustless Registration**: A subledger may register with any AO token process + without that process needing to be aware of the subledger protocol, nor the + security properties that it enforces. Instead, users that wish to participate + in a subledger process network with security properties that they deem + acceptable may do so at-will. Processes that do choose to participate may + maintain an index of known ledgers, allowing tokens within them to be shown + as fungible with the root ledger's tokens in user interfaces, etc. + +## 5.

The `access-control' message verifies the request (e.g., checks cookies, +%%% provided authentication credentials, etc.). +%%% 4.

Options: +%%% - `client': The secret is generated on the server, but not persisted. +%%% The full secret key is returned for the user to store. +%%% - `in-memory': The wallet is generated on the server and persisted only +%%% in local memory, never written to disk. +%%% - `non-volatile': The wallet is persisted to non-volatile storage on +%%% the node. The store used by this option is segmented from +%%% the node's main storage, configurable via the `priv_store' +%%% node message option. +%%% - `controllers' (optional): A list of controllers that may access the +%%% secret. Defaults to the node's `wallet_admin' option if set, +%%% or its operator address if not. +%%% - `required-controllers' (optional): The number of controllers that must +%%% sign the secret for it to be valid.

 %%% Before writing a message to the store, we convert it to Type-Annotated
 %%% Binary Messages (TABMs), such that each of the keys in the message is
 %%% either a map or a direct binary.
+%%% 
+%%% Nested keys are lazily loaded from the stores, such that large deeply
+%%% nested messages where only a small part of the data is actually used are
+%%% not loaded into memory unnecessarily. In order to ensure that a message is
+%%% loaded from the cache after a `read', we can use the `ensure_loaded/1' and
+%%% `ensure_all_loaded/1' functions. Ensure loaded will load the exact value
+%%% that has been requested, while ensure all loaded will load the entire 
+%%% structure of the message into memory.
+%%% 
+%%% Lazily loadable `links' are expressed as a tuple of the following form:
+%%% `{link, ID, LinkOpts}', where `ID' is the path to the data in the store,
+%%% and `LinkOpts' is a map of suggested options to use when loading the data.
+%%% In particular, this module ensures to stash the `store' option in `LinkOpts',
+%%% such that the `read' function can use the correct store without having to
+%%% search unnecessarily. By providing an `Opts' argument to `ensure_loaded' or
+%%% `ensure_all_loaded', the caller can specify additional options to use when
+%%% loading the data -- overriding the suggested options in the link.

+%%% @doc A testing framework for AO-Core devices and HyperBEAM components built
+%%% upon the principles of property-based testing. Rather than testing specific
+%%% input and output pairs, `hb_invariant' allows us to instead focus on 
+%%% defining invariant properties that should hold true for all valid inputs.
+%%% `hb_invariant' gives us tools to quickly and easily generate random inputs
+%%% (states, requests, node messages, etc.) to our components and then test that
+%%% the stated properties hold true for each of them.
+%%% 
+%%% ## Execution Types.
+%%% 
+%%% Executions can come in a variety of forms:
+%%% 
+%%% - AO-Core device key relationships: Allowing us to define properties 
+%%%   that should hold true for all `Base`, `Request`, node messages, and their
+%%%   corresponding `Result` messages.
+%%% - AO-Core device state machines: Allowing us to generate random initial
+%%%   states and sequences of requests, ensuring that a set of properties hold
+%%%   true at all times.
+%%% - Comparisons between two AO-Core device state machines: As above, except
+%%%   allowing us to define two generators for initial states, such that the 
+%%%   functionality of one device can easily be compared to another. Properties
+%%%   in such tests receive not only the 'pre' and 'post' states for the primary
+%%%   state machine, but also the corresponding values for the reference machine.
+%%% - Direct Erlang function executions: Possible in each of the above cases,
+%%%   `hb_invariant' allows us to compute Erlang functions rather than AO-Core
+%%%   (`ao(Base, Req, Opts)') invocations, if preferred. This allows us to utilize
+%%%   `hb_invariant' to test HyperBEAM itself, as well as devices resident
+%%%   inside it.
+%%% 
+%%% ## Execution Flow.
+%%% 
+%%% There are two primary invocation methods for `hb_invariant': `forall/1' and
+%%% `state_machine/1'. Because the state machine is sufficiently general to cover
+%%% all cases, under-the-hood `forall' is simply a wrapper around `state_machine'
+%%% that sets the length of the request sequence to `1'. A consequence of this
+%%% is that all invocations are able to utilize the full set of parameters to
+%%% control the execution.
+%%% 
+%%% The state machine executor always takes a `Specification' message as an
+%%% argument, and operates in a series of stages:
+%%% 
+%%% ```
+%%% 1. Specification normalization: All non-mandatory fields are filled in with
+%%%    default values, internal state keys are initialized in the `Spec', and
+%%%    initial seeding of the PRNG (`rand' module) is performed.
+%%% 2. Repeat for each of the `Spec/runs' of the state machine:
+%%% 2.1* Generate a node message (`Opts').
+%%% 2.2* Generate an initial state (`Base' message) for the execution.
+%%% 2.3* Generate an initial model state (`Model' message) for the execution, if
+%%%      applicable.
+%%% 2.4. For each element of request sequence `Spec/length`:
+%%% 2.4.1* Generate a request message (`Request' message) for the execution.
+%%% 2.4.2* Execute the request message against the current state (and model state,
+%%%        if applicable), resulting in a `Result' message.
+%%% 2.4.3. For each of the `Spec/properties':
+%%% 2.4.3.1. Attempt to invoke the property function with the prior state(s), request,
+%%%        result(s), and options.
+%%% 2.4.3.2. If the property function returns `true', continue to the next property.
+%%% 2.4.3.3. If the property function returns `false', fail and return details of
+%%%          the executed sequence and error encountered.
+%%% 2.4.3.4. If the property function lacks a function clause matching the call
+%%%          the failure is ignored. This allows callers to easily define which
+%%%          states are relevant for a given property simply with patterns and 
+%%%          guards in the function head.
+%%% 2.4.4. Apply `Spec/next' to the state and model state, if applicable, resulting
+%%%        in a new state and model state. If no `next' function is provided, the
+%%%        result of the request stage is used in the next iteration of the loop.
+%%% 3. Return `ok' if all properties were enforced successfully, otherwise return
+%%%    details of the executed sequence and the error encountered.
+%%% '''
+%%% `*' markers above indicate that prior to the execution of a stage, the `rand'
+%%% module's PRNG is seeded with a value derived from the global seed (either
+%%% provided or generated at start time), the run number, the current request
+%%% count, and the current stage. This allows for reproducibility of the execution
+%%% sequences. See `Controlled Randomness' below for more details.
+%%% 
+%%% ## Generators.
+%%% 
+%%% `hb_invariant' supports a number of different types of `generators', utilized
+%%% to derive each input in execution sequences. Supported generator forms are
+%%% as follows:
+%%% 
+%%% - Lists: Lists of generators of other forms, from which one one member is
+%%%   randomly selected and executed as if it was provided directly.
+%%% - Functions: Arbitrary Erlang functions, invoked with a specific set of
+%%%   arguments depending on the type of generator and the context.
+%%% - Explicit values: A simple constant value or message, used without execution.
+%%% 
+%%% Generators of these forms may be provided by the caller for each of the 
+%%% keys listed below. Their names and function signatures are as follows:
+%%% - `opts(Spec)': A generator for the node message to use for a `run' of the

+%%% - `Spec/states': A generator for initial (`Base') states, executed per `run'.
+%%% - `Spec/models': A generator for initial _model_ states, executed per `run'.
+%%% - `Spec/requests': Generator of `Request's in the state transformation sequence.

+%%% `rand' module with a value derived from a provided global seed, or a unique
+%%% value per invocation of the state machine executor. In event of errors, the
+%%% initial global seed is provided to the user such that issues that arose may
+%%% be reproduced.
+%%% 
+%%% Value generators for the following types are provided:
+%%% - `int/0': Generate a random integer between 0 and the maximum 'small'
+%%%   (non-bignum) integer value.
+%%% - `int/1': Generate a random integer between 0 and the given maximum value.
+%%% - `int/2': Generate a random integer between the given values.
+%%% - `float/0': Generate a random float between 0 and the maximum float value.
+%%% - `float/1': Generate a random float between 0 and the given maximum value.
+%%% - `string/0': Generate a random string of a given length.
+%%% - `string/1': Generate a random string of a given length.
+%%% - `string/4': Generate a random string of a given length, with a give
+%%%   minimum and maximum character values, and a list of forbidden characters.

+%%% @doc An abstraction for working with maps in HyperBEAM, matching the

+%%% links as they are encountered. These functions must be used extremely
+%%% carefully. In virtually all circumstances, the `hb_ao:resolve/3' or
+%%% `hb_ao:get/3' functions should be used instead, as they will execute the
+%%% full AO-Core protocol upon requests (normalizing keys, applying the
+%%% appropriate device's functions, as well as resolving links). By using this
+%%% module's functions, you are implicitly making the assumption that the message
+%%% in question is of the `~message@1.0' form, ignoring any other keys that its
+%%% actual device may present. This module is intended for the extremely rare
+%%% circumstances in which the additional overhead of the full AO-Core
+%%% execution cycle is not acceptable, and the data in question is known to
+%%% conform to the `~message@1.0' form.
+%%%
+%%% If you do not understand any/all of the above, you are in the wrong place!
+%%% Utilise the `hb_ao' module and read the documentation therein, saving
+%%% yourself from the inevitable issues that will arise from using this
+%%% module without understanding the full implications. You have been warned.
