Trait to implement for actual cache implementations

Required Associated Types§

type Error

Required Methods§

Source

fn fetch<T: Cacheable>( &mut self, key: &String, ) -> Result<Option<T>, Self::Error>

Source

fn save<T: Cacheable>( &mut self, key: &String, item: &T, ttl: Duration, ) -> Result<(), Self::Error>

Source

fn delete(&mut self, key: &String) -> Result<(), Self::Error>

Source

fn clear(&mut self) -> Result<(), Self::Error>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
