A cache.

Required Methods

fn get_with<'life0, 'async_trait>( &'life0 self, key: String, future: Box<dyn Future<Output = T> + Send>, ) -> Pin<Box<dyn Future<Output = Result<T, CacheError>> + Send + 'async_trait>>

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

Gets a cached value.

If a cached value is not found, it awaits the given future and sets its resulting value into the cache and returns the value.

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), CacheError>> + Send + 'async_trait>>

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

Removes a cached value corresponding to the given key.
