Expand description

Persistent session storage.

Implementations must be safe to clone cheaply — sessions are accessed on every request, so the trait is invoked from inside hot middleware paths.

Required Methods§

Source

fn load<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Option<Vec<u8>>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Reads a session blob keyed by id. Returns None if the session does not exist or has expired.

Source

fn store<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, data: Vec<u8>, ttl: Duration, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Inserts or replaces the session blob for id with the configured TTL.

Source

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Removes the session, returning whether the key existed.

Provided Methods§

Source

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

Optional sweep hook. The default in-memory store schedules its own janitor; remote backends typically rely on TTL expiry inside the underlying database (e.g. Redis EXPIRE).

Dyn Compatibility§

This trait is dyn compatible.

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