Trait Store 

pub trait Store<K, V> {
    // Required methods
    fn get(&self, key: &K) -> Option<&V>;
    fn get_mut(&mut self, key: &K) -> Option<&mut V>;
    fn insert(&mut self, key: K, value: V) -> Option<V>;
    fn remove(&mut self, key: &K) -> Option<V>;
}

Required Methods

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

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

fn insert(&mut self, key: K, value: V) -> Option<V>

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

Dyn Compatibility

This trait is dyn compatible.

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