Trait std::container::Map

pub trait Map<K, V>: Container {
    fn find<'a>(&'a self, key: &K) -> Option<&'a V>;

    fn contains_key(&self, key: &K) -> bool { ... }
}

A map is a key-value store where values may be looked up by their keys. This trait provides basic operations to operate on these stores.

Required Methods

`fn find<'a>(&'a self, key: &K) -> Option<&'a V>`

Return a reference to the value corresponding to the key

Provided Methods

`fn contains_key(&self, key: &K) -> bool`

Return true if the map contains a value for the specified key
