Trait for persisting session state across process restarts.

Implementations might write to the filesystem, Redis, Firestore, etc.

Required Methods

fn save<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_id: &'life1 str, snapshot: &'life2 SessionSnapshot, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Save a session snapshot.

fn load<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<SessionSnapshot>, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Load a previously saved session snapshot.

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

Delete a saved session.
