Trait for pluggable session extension providers.

Providers receive lifecycle callbacks for sessions that carry their declared key in the extensions map. Provider errors are never fatal to session lifecycle (invariant E-1).

Required Methods

fn key(&self) -> &str

fn on_session_start<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_id: &'life1 str, extensions: &'life2 HashMap<String, Vec<u8>>, ) -> Pin<Box<dyn Future<Output = Result<(), ExtensionError>> + Send + 'async_trait>>

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

fn on_session_terminal<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, outcome: SessionOutcome, ) -> Pin<Box<dyn Future<Output = Result<(), ExtensionError>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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