Trait ObjectCache 

pub trait ObjectCache<K, V>: Send + Sync {
    // Required methods
    fn get(&self, key: &K) -> Option<V>;
    fn set(&self, key: K, value: V);
}

A trait for caching in-memory objects of given type.

Notes

ObjectCache will store deeply nested objects, such as Manifest, which contains Schema. Please ensure that the cache stores the object in memory as-is, without attempting to serialize it, as serialization could be extremely expensive.

Required Methods

fn get(&self, key: &K) -> Option<V>

Gets an object from the cache by its key.

fn set(&self, key: K, value: V)

Sets an object in the cache with the given key and value.

Dyn Compatibility

This trait is dyn compatible.

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