:param match: The matcher to satisfy, or an expected value for

:py:func:`~hamcrest.core.core.isequal.equal_to` matching.

This matcher invokes the :py:func:`str` function on the evaluated object to
|
|
get its length, passing the result to a given matcher for evaluation. If
|
|
the ``match`` argument is not a matcher, it is implicitly wrapped in an
|
|
:py:func:`~hamcrest.core.core.isequal.equal_to` matcher to check for
|
|
equality.

Examples::
|
|
|
|
has_string(starts_with('foo'))
|
|
has_string('bar')
