Examples of how to use Tokio
This directory contains a number of examples showcasing various capabilities of
All examples can be executed with:
cargo run --example $name
A high level description of each example is:
hello_world- a tiny server that writes "hello world" to all connected clients and then terminates the connection, should help see how to create and initialize
echo- this is your standard TCP "echo server" which accepts connections and then echos back any contents that are read from each connected client.
print_each_packet- this server will create a TCP listener, accept connections in a loop, and put down in the stdout everything that's read off of each TCP connection.
echo-udp- again your standard "echo server", except for UDP instead of TCP. This will echo back any packets received to the original sender.
connect- this is a
nc-like clone which can be used to interact with most other examples. The program creates a TCP connection or UDP socket to sends all information read on stdin to the remote peer, displaying any data received on stdout. Often quite useful when interacting with the various other servers here!
chat- this spins up a local TCP server which will broadcast from any connected client to all other connected clients. You can connect to this in multiple terminals and use it to chat between the terminals.
chat-combinator- Similar to
chat, but this uses a much more functional programming approach using combinators.
proxy- an example proxy server that will forward all connected TCP clients to the remote address specified when starting the program.
tinyhttp- a tiny HTTP/1.1 server which doesn't support HTTP request bodies showcasing running on multiple cores, working with futures and spawning tasks, and finally framing a TCP connection to discrete request/response objects.
tinydb- an in-memory database which shows sharing state between all connected clients, notably the key/value store of this database.
udp-client- a simple
manual-runtime- manually composing a runtime.
