Tokio Chat Server Example

This is a more involved example of using tokio to write a concurrent application. This chat server demonstrates

• how to handling states in streams and futures
• how to use data structures that need to be shared between threads (e.g. to keep track of sessions)
• how to "broadcast" to streams
• how to shutdown a stream early

the server itself features

• private messages
• "commands"

How to try it

First, open a terminal and compile with cargo compile. Then run cargo run. Open two more terminals, and in each one, run netcat localhost 8080.

You can "log in" by typing a name and pressing ENTER. Then you can send messages by entering some string and then hitting ENTER.

It's also possible to send a "private message" to user <name> by typing in /msg <name> <message>.
