Expand description

Where values live. Every method answers for one key; a failure is the store’s own (a connection lost), never a miss.

Required Methods§

Source

fn name(&self) -> &'static str

The driver’s name, as cache.store names it.

Source

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

Source

fn put<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, entry: Entry, ttl: Duration, ) -> Pin<Box<dyn Future<Output = CoreResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn add<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, entry: Entry, ttl: Duration, ) -> Pin<Box<dyn Future<Output = CoreResult<bool>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stores only when the key is absent; true when it did.

Source

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

true when a value was there.

Source

fn flush<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = CoreResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility§

This trait is dyn compatible.

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