Required Methods

fn get_with_timeout<Q>(&self, k: &Q) -> Option<&V>

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

fn get_with_timeout_mut<Q>(&mut self, k: &Q) -> Option<&mut V>

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

fn insert_with_timeout( &mut self, k: K, v: V, timeout: Option<Duration>, ) -> Option<V>

fn remove_expired_values(&mut self)

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.
