python313-immutables - Immutable Collections
- Description:
An immutable mapping type for Python.
The underlying datastructure is a Hash Array Mapped Trie (HAMT) used
in Clojure, Scala, Haskell, and other functional languages. This
implementation is used in CPython 3.7 in the contextvars module (see
PEP 550 and PEP 567 for more details).
Immutable mappings based on HAMT have O(log N) performance for both
set() and get() operations, which is essentially O(1) for relatively
small mappings.
