#define CHATPACKETSLEGACY_H

// FROZEN ORACLE - DO NOT EDIT.
// Verbatim copies of the hand written chat packet code that dNet/ChatPackets.h replaced (dNet/ChatPackets.cpp,
// dChatServer/{ChatPacketHandler,ChatIgnoreList,TeamContainer,PlayerContainer}.cpp, dWorldServer/WorldServer.cpp and
// the dGame senders at f8f977f8). Only the namespace changed, except:
//  - senders that wrote to Game::chatServer (a RakPeer the tests don't have) write into `bitStream` instead;
//  - the parts of handlers that write or read a packet are copied on their own, with the state they used passed in;
//  - old readers return what they read in a struct instead of acting on it.
// The byte-equality tests send the same inputs through these and through the new structs and require identical
// bytes, so the wire format is pinned even after the production code is deleted.
