    Documentation

    Installation

    First add this to your Cargo.toml:

    [dependencies]
    coap = "0.3"

    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());
    }
