multidict implementation
Project description
=========
multidict
=========
Multidicts are useful for working with HTTP headers, URL
query args etc.
The code was extracted from aiohttp library.
Introduction
------------
*HTTP Headers* and *URL query string* require specific data structure:
*multidict*. It behaves mostly like a :class:`dict` but it can have
several *values* for the same *key*.
:mod:`multidict` has four multidict classes:
:class:`MultiDict`, :class:`MultiDictProxy`, :class:`CIMultiDict`
and :class:`CIMultiDictProxy`.
Immutable proxies (:class:`MultiDictProxy` and
:class:`CIMultiDictProxy`) provide a dynamic view on the
proxied multidict, the view reflects underlying collection changes. They
implement the :class:`~collections.abc.Mapping` interface.
Regular mutable (:class:`MultiDict` and :class:`CIMultiDict`) classes
implement :class:`~collections.abc.MutableMapping` and allows to change
their own content.
*Case insensitive* (:class:`CIMultiDict` and
:class:`CIMultiDictProxy`) ones assumes the *keys* are case
insensitive, e.g.::
>>> dct = CIMultiDict(a='val')
>>> 'A' in dct
True
>>> dct['A']
'val'
*Keys* should be a :class:`str`.
The library has optional Cython optimization for sake of speed.
