Available on crate feature service only.

Extension trait providing ergonomic cache methods for any Service<CacheOperation>.

This allows middleware-wrapped cache services to be used with the same simple API as a direct Cache.

Required Methods

fn get( &self, key: &K, ) -> impl Future<Output = Result<Option<CacheEntry<V>>, Error>> + Send

Retrieves a value from the cache.

fn insert( &self, key: K, entry: CacheEntry<V>, ) -> impl Future<Output = Result<(), Error>> + Send

Inserts a value into the cache.

fn invalidate(&self, key: &K) -> impl Future<Output = Result<(), Error>> + Send

Invalidates (removes) a value from the cache.

fn clear(&self) -> impl Future<Output = Result<(), Error>> + Send

Clears all entries from the cache.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementors

impl<K, V, S> CacheServiceExt<K, V> for S

where K: Clone + Send + Sync, V: Clone + Send + Sync, S: Service<CacheOperation<K, V>, Out = Result<CacheResponse<V>, Error>> + Send + Sync,
