Introduction
------------
The API is designed to be nearly identical to the built-in ``functools.cached_property`` class,
except for the additional ``under_cached_property`` class which uses ``self._cache``
instead of ``self.__dict__`` to store the cached values and prevents ``__set__`` from being called.
For full documentation please read https://propcache.readthedocs.io.
Installation
------------
::
$ pip install propcache
The library is Python 3 only!
PyPI contains binary wheels for Linux, Windows and MacOS. If you want to install
``propcache`` on another operating system where wheels are not provided,
the the tarball will be used to compile the library from
the source code. It requires a C compiler and and Python headers installed.
To skip the compilation you must explicitly opt-in by using a PEP 517
configuration setting ``pure-python``, or setting the ``PROPCACHE_NO_EXTENSIONS``
environment variable to a non-empty value, e.g.:
.. code-block:: console
$ pip install propcache --config-settings=pure-python=false
Please note that the pure-Python (uncompiled) version is much slower. However,
PyPy always uses a pure-Python implementation, and, as such, it is unaffected
by this variable.
