Documentation

Installation

First add this to your Cargo.toml:

[dependencies]
coap = "0.2.0"

Then, add this to your crate root:

extern crate coap;

Example

Server:

extern crate coap;

use std::io;
use coap::packet::*;
use coap::{CoAPServer, CoAPClient};

fn request_handler(req: Packet, _resp: CoAPClient) {
	println!("Receive request: {:?}", req);
}

fn main() {
	let addr = "127.0.0.1:5683";

	let mut server = CoAPServer::new(addr).unwrap();
	server.handle(request_handler).unwrap();
		
	println!("Server up on {}", addr);
    println!("Press any key to stop...");
	io::stdin().read_line(&mut String::new()).unwrap();

	println!("Server shutdown");
}

Client:

extern crate coap;

use coap::packet::*;
use coap::CoAPClient;

fn main() {
	let url = "coap://127.0.0.1:5683/Rust";
	println!("Client request: {}", url);

	let response: Packet = CoAPClient::request(url).unwrap();
	println!("Server reply: {}", String::from_utf8(response.payload).unwrap());
}
