Trait RawStoreMut 

pub trait RawStoreMut<K, V>: RawStore<K, V> {
    // Required methods
    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>;
}

RawStoreMut extends the RawStore trait by introducing various mutable operations and accessors for elements within the store.

Required Methods

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

retrieves a mutable reference to a value by key

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

inserts a key-value pair into the store

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

removes a key-value pair from the store by key

Dyn Compatibility

This trait is dyn compatible.

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