Trait MutableMap 

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

Trait abstracting over map operations needed by apply_inverted_lookup and apply_with_update. Both BTreeMap and imbl::OrdMap implement this.

Required Methods

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".
