Trait Cached

pub trait Cached: Sized {
    type Cache: Clone;

    // Required methods
    fn load(cache: &Self::Cache) -> Self;
    fn cache(self, group: Group, previous: Option<Self::Cache>) -> Self::Cache;
}

A piece of data that can be cached.

Required Associated Types

type Cache: Clone

The type of cache produced.

Required Methods

fn load(cache: &Self::Cache) -> Self

Loads the Cache into a proper instance.

fn cache(self, group: Group, previous: Option<Self::Cache>) -> Self::Cache

Caches this value, producing its corresponding Cache.

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.
