Required Methods§

Source

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

Source

fn put<'life0, 'async_trait>( &'life0 self, key: String, value: Bytes, hint: FillHint, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Provided Methods§

Source

fn disk_stats(&self) -> Option<BackendDiskStats>

Disk write-path counters, for the saturation monitor’s per-second gauges. Defaulted to None so backends without a disk tier (e.g. MemoryBackend) need no override.

Dyn Compatibility§

This trait is dyn compatible.

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