Trait CloneCached

pub trait CloneCached<K, V> {
    // Required method
    fn cache_get_expired<Q>(&mut self, _key: &Q) -> (Option<V>, bool)
       where K: Borrow<Q>,
             Q: Hash + Eq + ?Sized;
}

Required Methods

fn cache_get_expired<Q>(&mut self, _key: &Q) -> (Option<V>, bool)

where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Attempt to retrieve a cached value and indicate whether that value was evicted.

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.
