This trait defines a key/value storage

Required Methods

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

Store a key / value

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

Retrieve a value. Return None if no value corresponds to the specified key

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

Delete a value and return it if found
