Middleware wrapping StateStore read and write operations.

Use for: encryption-at-rest, audit trails, caching, access control.

Required Methods

fn write<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, scope: &'life1 Scope, key: &'life2 str, value: Value, options: Option<&'life3 StoreOptions>, next: &'life4 dyn StoreWriteNext, ) -> Pin<Box<dyn Future<Output = Result<(), StateError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

Intercept a state write.

Provided Methods

fn read<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, scope: &'life1 Scope, key: &'life2 str, next: &'life3 dyn StoreReadNext, ) -> Pin<Box<dyn Future<Output = Result<Option<Value>, StateError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Intercept a state read. Default: pass through.
