Trait CacheBackend 

pub trait CacheBackend: Send + Sync {
    // Required methods
    fn get(&self, namespace: &str, key: &str) -> Option<Vec<u8>>;
    fn put(
        &self,
        namespace: &str,
        key: &str,
        value: Vec<u8>,
        ttl: Option<Duration>,
    );
    fn invalidate(&self, namespace: &str);
}

A pluggable cache tier. namespace is the cache declaration’s name so invalidate can flush exactly one cache’s entries. The enterprise injects a Redis impl of this; the OSS default is InProcessCache.

Required Methods

fn get(&self, namespace: &str, key: &str) -> Option<Vec<u8>>

fn put(&self, namespace: &str, key: &str, value: Vec<u8>, ttl: Option<Duration>)

fn invalidate(&self, namespace: &str)

Flush every entry belonging to namespace (an emit on an invalidate_on: channel triggers this).

Dyn Compatibility

This trait is dyn compatible.

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