Trait Map 

pub trait Map<K, V>:
    Keyed<Key = K, Item = V>
    + Len
    + for<'a> Get<&'a K>
    + for<'a> GetKeyValue<&'a K> { }

Imutable map data structure.

A map is an unordered collection storing key-value pairs, indexed by the key.

This trait is not dyn compatible.

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