Pluggable cache backend.

Implementations decide eviction, TTL, and persistence. The default MemoryCache is unbounded and lives only as long as the process.

Required Methods

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 K, ) -> Pin<Box<dyn Future<Output = Option<V>> + Send + 'async_trait>>

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

Look up a value. None if not present.

fn set<'life0, 'async_trait>( &'life0 self, key: K, value: V, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Store a value.
