    You can retrieve these via :meth:`Guild.audit_logs`,

    .. collapse:: operations

        .. describe:: x == y

            Checks if two entries are equal.

        .. describe:: x != y

            Checks if two entries are not equal.

        .. describe:: hash(x)

            Returns the entry's hash.

    .. versionchanged:: 1.7
        Audit log entries are now comparable and hashable.

    Attributes
    ----------
    action: :class:`AuditLogAction`
        The action that was done.
    user: Optional[Union[:class:`Member`, :class:`User`, :class:`Object`]]
        The user who initiated this action. Usually :class:`Member`\\, unless gone
        then it's a :class:`User`.

        .. versionchanged:: 2.8
            May now be an :class:`Object` if the user could not be found.
    id: :class:`int`
        The entry ID.
    target: Any
        The target that got changed. The exact type of this depends on
        the action being done.
    extra: Any
        Extra information that this entry has that might be useful.
        For most actions, this is ``None``. However in some cases it
        contains extra information. See :class:`AuditLogAction` for
        which actions have this field filled out.
    reason: Optional[:class:`str`]
        The reason this action was done.
