Trait fixed_map::Storage

pub trait Storage<K, V>: Default {
    fn insert(&mut self, key: K, value: V) -> Option<V>;
    fn get(&self, key: &K) -> Option<&V>;
    fn get_mut(&mut self, key: &K) -> Option<&mut V>;
    fn remove(&mut self, key: &K) -> Option<V>;
    fn for_each_value<F>(&self, f: F)
    where
        F: FnMut(&V);
}

The trait defining how storage works.

Type Arguments

• K is the key being stored.
• V is the value being stored.

Required Methods

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

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

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

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

fn for_each_value<F>(&self, f: F)where
    F: FnMut(&V),

Call the given closure for each key and value combination that is present in storage.
