Expand description

Implementations must serialize calls and commit before complete returns. A missing outcome is an instruction to execute, regardless of idempotency.

Required Methods§

Source

fn begin<'life0, 'life1, 'async_trait>( &'life0 self, operation: &'life1 str, fingerprint: [u8; 32], ) -> Pin<Box<dyn Future<Output = Result<EffectCall, HistoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn complete<'life0, 'life1, 'async_trait>( &'life0 self, call: &'life1 EffectCall, outcome: RecordedOutcome, ) -> Pin<Box<dyn Future<Output = Result<(), HistoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn ensure_history_consumed<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), HistoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Verify that no effect is pending and all recorded calls have been consumed.

Provided Methods§

Source

fn take_storage_fuel(&self) -> u64

Additional persistence work, reported once and settled by the host boundary. Storage must not reject a completed native outcome because fuel ran out.

Source

fn drain<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), HistoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Finish owned persistence I/O before releasing execution resources.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
