5. Submission of Contributions. Unless You explicitly state otherwise,
131+
any Contribution intentionally submitted for inclusion in the Work

incidental, or consequential damages of any character arising as a

result of this License or out of the use or inability to use the
160+
Work (including but not limited to damages for loss of goodwill,
161+
work stoppage, computer failure or malfunction, or any and all
162+
other commercial damages or losses), even if such Contributor
163+
has been advised of the possibility of such damages.
164+
165+

170+
on Your own behalf and on Your sole responsibility, not on behalf
171+
of any other Contributor, and only if You agree to indemnify,
172+
defend, and hold each Contributor harmless for any liability
173+

# Promise x Tokio = Prokio
2+
3+
An asynchronous runtime compatible with WebAssembly and non-WebAssembly targets.
4+
5+
# Rationale
6+
7+
When designing components and libraries that works on both WebAssembly targets backed by
8+
JavaScript Runtime and non-WebAssembly targets with Native Runtimes. Developers usually face
9+
challenges that requires applying multiple feature flags throughout their application:
10+
11+
1. Select I/O and timers that works with the target runtime.
12+
2. Native Runtimes usually require `Send` futures and WebAssembly types are usually `!Send`.
13+
14+
# Implementation
15+
16+
To alleviate these issues, Prokio implements a single-threaded runtime that executes `?Send`
17+
(`Send` or `!Send`) futures.
18+
19+
On platforms with multi-threading support, prokio spawns multiple independent runtimes proportional
20+
to the CPU core number. When tasks are spawned with a runtime handle, it will randomly select a
21+
worker thread from the internal pool. All tasks spawned with `spawn_local` will run on the same thread
22+
as the thread the task was running. When the runtime runs in a WebAssembly target, all
23+
tasks will be scheduled on the main thread.
24+
25+
This runtime is designed in favour of IO-bounded workload with similar runtime cost.
26+
When running I/O workloads, it would produce a slightly better performance as tasks are
27+
never moved to another thread. However, If a worker thread is busy,
28+
other threads will not be able to steal tasks scheduled on the busy thread.
29+
When you have a CPU-bounded task where CPU time is significantly
30+
more expensive, it should be spawned with a dedicated thread (or Web Worker) and communicates
31+
with the application using channels.
32+
33+
Prokio provides the following components:
34+
35+
1. A Task Scheduler that is capable of running non-Send tasks.
36+
2. A Timer that is compatible with the scheduler backend.
37+
3. Task Synchronisation Mechanisms.
38+
39+
# Runtime Backend
40+
41+
Prokio runtime is implemented with different runtimes depending on the target platform and can use
42+
all features (timers / IO / task synchronisation) from the selected native runtime:
43+
44+
- `wasm-bindgen-futures` (WebAssembly targets)
45+
- `tokio` (non-WebAssembly targets)
