Expand description

Minimal async cache storage operations shared by all store adapters.

Required Methods§

Source

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

Retrieve a string value by key.

Source

fn set<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, val: &'life2 str, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = AppResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store a string value with an optional TTL.

Duration::ZERO is invalid. Stores should honor sub-second TTLs with at least millisecond precision; durations below one millisecond may be rounded up.

Source

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = AppResult<bool>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete a key and report whether it existed.

Source

fn exists<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = AppResult<bool>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check whether a key currently exists.

Dyn Compatibility§

This trait is dyn compatible.

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