frozentype 0.6

Package frozentype provide some frozen python types (frozendict (C based) and frozenmap (Cython based))

=========
frozentype
=========

**frozentype** is `MIT Licensed <http://opensource.org/licenses/MIT>`_ python library.
It implements some frozen python types: ``frozendict`` type (in C) and ``FrozenDict``, ``FrozenMap`` classes (in Cython).

* `frozendict` is read-only and hashable dictionary (C based).
* `FrozenMap` is read-only mapping object wrapped around a mutable mapping object (Cython based).
* `FrozenDict` is read-only and hashable dictionary (Cython based).

This library actually is an attempt to proof the concept of fast frozendict (C/Cython based).

Main repository for ``frozentype``
is on `bitbucket <https://bitbucket.org/intellimath/frozentype>`_.

Quick start:
------------


First load inventory::

>>> from frozentype import frozendict, FrozenDict

Simple example::

>>> fd = frozendict(a=1,b=2,c=3)
>>> fd
frozendict({'a': 1, 'b': 2, 'c': 3})
>>> fd['a']
1
>>> fd['a'] = 10
........
TypeError: 'frozentype._frozendict.frozendict' object does not support item assignment
>>> del fd['a']
.........
TypeError: 'frozentype._frozendict.frozendict' object does not support item deletion
>>> fd.pop('a')
.........
AttributeError: 'frozentype._frozendict.frozendict' object has no attribute 'pop'


>>> fd = FrozenDict(a=1,b=2,c=3)
>>> print(fp)
FrozenDict({'a': 1, 'b': 2, 'c': 3})
>>> fd['a']
1
>>> fd['a'] = 10
........
TypeError: 'frozentype.frozendict.FrozenDict' object does not support item assignment
>>> del fd['a']
.........
TypeError: 'frozentype.frozendict.FrozenDict' object does not support item deletion
>>> fd.pop('a')
.........
AttributeError: 'frozentype.frozendict.FrozenDict' object has no attribute 'pop'


Changes:
--------

** 0.6 ** (migrate from project intellimath/frozenmap)

* Add C implementation for `frozendict`.
* Add tests for frozendict type.

**0.5** Initial version
