This module defines the persistent storage layout for the QuickEx contract. -//! All long-term data is stored via the [`DataKey`] enum, which centralises key -//! construction and ensures type-safe storage access. -//! -//! ## Key Layout -//! -//! | Key Variant | Value Type | Description | -//! |------------------------|----------------|-------------| -//! | [`Escrow`](DataKey::Escrow) | `EscrowEntry` | Escrow entry keyed by commitment hash (32 bytes). One entry per unique deposit. | -//! | [`EscrowCounter`](DataKey::EscrowCounter) | `u64` | Global monotonic counter for escrow creation. | -//! | [`Admin`](DataKey::Admin) | `Address` | Contract admin address.

(`SHA256(owner || amount || salt)`). The stored [`EscrowEntry`] contains token, amount, owner, -//! status, and created_at. -//! - **Admin ↔ Paused**: Admin can set the paused flag. Both are singleton keys. -//! - **PrivacyLevel ↔ PrivacyHistory**: Same account may have both; level is current, history is append-only. -//! - **PrivacyLevel / PrivacyHistory ↔ privacy_enabled**: Separate APIs; level-based vs boolean. Both persist per `Address`. -//! -//! ## Backwards Compatibility -//! -//! For future upgrades: -//! - **Do not** remove or change the discriminant of existing [`DataKey`] variants. -//! - **Add** new variants for new keys; they will not collide with existing ones. -//! - **Value layout**: Changing `EscrowEntry` fields may require migration logic; adding optional -//! fields can be done carefully with defaults. - -use soroban_sdk::{contracttype, Address, Bytes, Env, Vec}; - -use crate::types::EscrowEntry; - // ----------------------------------------------------------------------------- -// Key constants (for keys not using DataKey) +// Pause helpers (feature-based API) // ----------------------------------------------------------------------------- -/// Symbol string for the boolean privacy-enabled flag. -/// Used as `(Symbol::new(env, PRIVACY_ENABLED_KEY), Address)` in persistent storage. -/// See [`crate::privacy`] module. -pub const PRIVACY_ENABLED_KEY: &str = "privacy_enabled"; - -// ----------------------------------------------------------------------------- -// DataKey enum – central key derivation -// ----------------------------------------------------------------------------- - -/// Storage keys for the contract. -/// -/// All persistent storage access should go through the helpers in this module. -/// Each variant maps to a distinct namespace; the Soroban runtime serialises -/// the enum discriminant and payload into the actual storage key. -#[contracttype] -#[derive(Clone)] -pub enum DataKey { - /// Escrow entry keyed by commitment hash (`Bytes`, typically 32 bytes). - Escrow(Bytes), - /// Global escrow counter (singleton). - EscrowCounter, - /// Admin address (singleton). - Admin, - /// Paused state (singleton). - Paused, - Pause, - /// Numeric privacy level per account. - PrivacyLevel(Address), - /// Privacy level change history per account. - PrivacyHistory(Address), - // Pause(u64) -} - -// ----------------------------------------------------------------------------- -// Escrow helpers -// ----------------------------------------------------------------------------- - -/// Put an escrow entry into storage. -/// -/// **Contract**: Overwrites any existing entry for the same commitment. -/// The commitment should be the 32-byte `SHA256(owner || amount || salt)` hash. -pub fn put_escrow(env: &Env, commitment: &Bytes, entry: &EscrowEntry) { - let key = DataKey::Escrow(commitment.clone()); - env.storage().persistent().set(&key, entry); -} - -/// Get an escrow entry from storage. -/// -/// **Contract**: Returns `None` if no escrow exists for the commitment. -pub fn get_escrow(env: &Env, commitment: &Bytes) -> Option { - let key = DataKey::Escrow(commitment.clone()); - env.storage().persistent().get(&key) -} - -/// Check if an escrow entry exists in storage. -#[allow(dead_code)] -pub fn has_escrow(env: &Env, commitment: &Bytes) -> bool { - let key = DataKey::Escrow(commitment.clone()); - env.storage().persistent().has(&key) -} - -/// Get the next escrow counter value. -/// -/// **Contract**: Returns 0 if never set.
