The typed conveniences every Cache gets.

Kept out of the object-safe trait so Arc<dyn Cache> still exists.

Provided Methods

fn get_json<'life0, 'life1, 'async_trait, T>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<T>>> + Send + 'async_trait>>

where T: 'async_trait + DeserializeOwned, Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

A value, deserialised from JSON.

fn put_json<'life0, 'life1, 'life2, 'async_trait, T>( &'life0 self, key: &'life1 str, value: &'life2 T, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where T: 'async_trait + Serialize + Sync, Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store a value as JSON.

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

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

A string value.

fn put_string<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, value: &'life2 str, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Store a string.

fn add_string<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, value: &'life2 str, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

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

Store a string only if the key is absent.

Cache::add with the encoding done for you. Atomic, like the method it calls.

fn decrement<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, by: i64, ) -> Pin<Box<dyn Future<Output = Result<i64>> + Send + 'async_trait>>

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

Subtract from a counter.

Dyn Compatibility

This trait is not dyn compatible.

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