Type Alias AtomMap 

pub type AtomMap<V> = HashMap<Atom, V, BuildHasherDefault<IdentityHasher>>;

A high-performance HashMap using Atom as the key.

This map is significantly faster than a standard HashMap because it uses the Atom’s pre-computed hash instead of hashing the string content on every lookup.
