Expand description

Accumulates observations for a logical session.

Required Methods§

Source

fn append_observation<'life0, 'async_trait>( &'life0 self, observation: MemoryObservation, ) -> Pin<Box<dyn Future<Output = Result<LedgerOutcome, MemoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Offer an observation to the ledger.

Source

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

Read the current candidate set.

Source

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

Close the ledger and hand its candidates to consolidation.
