Trait Implementations

impl<J: Journal> ReadJournal for SimpleReadJournal<J>

fn events_by_persistence_id<'life0, 'life1, 'async_trait>( &'life0 self, persistence_id: &'life1 str, from: u64, to: u64, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

Replay events for a single persistence id, sequence-number bounded.

fn events_by_tag<'life0, 'life1, 'async_trait>( &'life0 self, tag: &'life1 str, offset: Offset, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

All events with a given tag, returned in offset order. Default impl is empty so backends without tag indexing don’t silently mis-behave.

fn all_persistence_ids<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, JournalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Distinct persistence ids known to the backend. Default impl returns empty (backends without an id index opt in).

fn current_events_by_persistence_id<'life0, 'life1, 'async_trait>( &'life0 self, persistence_id: &'life1 str, from: u64, to: u64, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

Snapshot variant of Self::events_by_persistence_id — default impl is identical (in-memory journals don’t tail).

fn current_events_by_tag<'life0, 'life1, 'async_trait>( &'life0 self, tag: &'life1 str, offset: Offset, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

fn current_persistence_ids<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, JournalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn events_as_of<'life0, 'life1, 'async_trait>( &'life0 self, pid: &'life1 str, _system_time_nanos: u128, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

FR-8 — bitemporal system-time as-of query: return the events for pid as they were known to the system at system_time_nanos, excluding any later-recorded restatement (no lookahead).

fn events_valid_as_of<'life0, 'life1, 'async_trait>( &'life0 self, pid: &'life1 str, _valid_time_nanos: u128, _system_time_nanos: u128, ) -> Pin<Box<dyn Future<Output = Result<Vec<EventEnvelope>, JournalError>> + Send + 'async_trait>>

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

FR-8 — full bitemporal slice: events for pid whose valid time is at or before valid_time_nanos, as known to the system at system_time_nanos. Distinguishes a corrected value (recorded later) from the value originally known at an earlier system time.
