Cross-session transcript store. All methods are owner-scoped: a given owner can never see another owner’s sessions.

Required Methods

fn ensure_session<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, owner: &'life1 str, session_id: &'life2 str, meta: &'life3 SessionMeta, ) -> Pin<Box<dyn Future<Output = Result<(), RecallError>> + Send + 'async_trait>>

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

Create/refresh the session row (idempotent).

fn append<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, owner: &'life1 str, session_id: &'life2 str, msg: &'life3 RecallMessage, ) -> Pin<Box<dyn Future<Output = Result<i64, RecallError>> + Send + 'async_trait>>

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

Append one message; returns the assigned id.

fn search<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, owner: &'life1 str, query: &'life2 str, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<SessionHit>, RecallError>> + Send + 'async_trait>>

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

Discovery: top sessions matching query, with snippet + bookends.

fn scroll<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, owner: &'life1 str, session_id: &'life2 str, around: i64, window: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<RecallMessage>, RecallError>> + Send + 'async_trait>>

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

Scroll: messages with id in [around - window, around + window].

fn recent<'life0, 'life1, 'async_trait>( &'life0 self, owner: &'life1 str, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<SessionMeta>, RecallError>> + Send + 'async_trait>>

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

Browse: the owner’s most recent sessions, newest first.

Dyn Compatibility

This trait is dyn compatible.

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