A rusty networking library for games.

Carrier pigeon builds on the standard library's TcpStream and UdpSocket types and handles all the serialization, sending, receiving, and deserialization. This way you can worry about what to send, and pigeon will worry about how to send it. This also allows you to send and receive different types of messages independently.

Add carrier-pigeon to your Cargo.toml:

carrier-pigeon = "0.3.0"

Also check out the Bevy plugin.



The documentation can be found on Docs.rs


A quickstart guide that goes in more detail is found at /quickstart.md


There is a simple chat program example in the examples/ directory. This contains a client and server command line programs.


  • Connection, response, disconnect messages built in and extremely flexible.
  • Configuration for buffer size, timeouts and more.
  • Send/Recv calls take an immutable reference allowing for parallelism.
  • Independent message sending.
  • TCP and UDP connections.
  • Client and Server types.
  • Built in serialization/deserialization.
  • Bevy integration (bevy-pigeon).

Planned Features

  • Server discovery.
  • Query support for server. (Optionally listen on another port and respond to query requests).
  • Optional buffering of TCP messages (Buffer all tcp messages sent, then write them all when a send_tcp method is called).
  • Compile messages into MsgTable using macros.
