          The action that was done.
      user: :class:`abc.User`
          The user who initiated this action. Usually a :class:`Member`\, unless gone

      id: :class:`int`
          The entry ID.
      target: Any
          The target that got changed. The exact type of this depends on
          the action being done.
      reason: Optional[:class:`str`]
          The reason this action was 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.
