Error
===================================================================

.. currentmodule:: gi.repository.GLib





.. class:: Error(message='unknown error', domain='pygi-error', code=0)
   :no-contents-entry:






The ``Error`` structure contains information about an error that has occurred.

Attributes
----------

.. rst-class:: interim-class

.. class:: Error
    :no-index:

    .. attribute:: domain

        The error domain, usually a string that you can convert to a
        GLib quark with :func:`~gi.repository.GLib.quark_from_string`.

    .. attribute:: code

        A numeric code that identifies a specific error within the domain.

    .. attribute:: message

        A human-readable description of the error.





Methods
-------

.. rst-class:: interim-class

.. class:: Error
   :no-index:


   .. method:: matches(domain, code)

      Returns :const:`True` if ``error`` matches ``domain`` and ``code``\, :const:`False`
      otherwise. In particular, when ``error`` is :const:`None`, :const:`False` will
      be returned.

      If ``domain`` contains a ``FAILED`` (or otherwise generic) error code,
      you should generally not check for it explicitly, but should
      instead treat any not-explicitly-recognized error code as being
      equivalent to the ``FAILED`` code. This way, if the domain is
      extended in the future to provide a more specific error code for
      a certain case, your code will still work.
