Module: MTProto::TL::MessageService

Defined in:
lib/mtproto/tl/objects/message_service.rb

Overview

The header of messageService#7a800e0a — the chat event (a join, a leave, a title change) that rides the same Vector as a plain message. The walk stops at the MessageAction, whose meaning belongs to the caller: it reads the action itself, from action_offset.
