A matcher is able to describe itself to give feedback when it fails.
Matcher implementations should *not* directly implement this protocol.
Instead, *extend* the :py:class:`~hamcrest.core.base_matcher.BaseMatcher`
class, which will ensure that the
:py:class:`~hamcrest.core.matcher.Matcher` API can grow to support new
features and remain compatible with all
:py:class:`~hamcrest.core.matcher.Matcher` implementations.
Nc C s t d��dS )as Evaluates the matcher for argument item.
If a mismatch is detected and argument ``mismatch_description`` is
provided, it will generate a description of why the matcher has not
accepted the item.
:param item: The object against which the matcher is evaluated.
:returns: ``True`` if ``item`` matches, otherwise ``False``.

item.
The description will be part of a larger description of why a matching
failed, so it should be concise.
This method assumes that ``matches(item)`` is ``False``, but will not
check this.
:param item: The item that the
:py:class:`~hamcrest.core.matcher.Matcher` has rejected.
:param mismatch_description: The description to be built or appended
to.
