Documentation

Installation

First add this to your Cargo.toml:

toml [dependencies] coap = "0.5"

Then, add this to your crate root:

rust extern crate coap;

Example

Server:

```rust extern crate coap;

use std::io; use coap::{CoAPServer, CoAPResponse, CoAPRequest};

fn request_handler(req: CoAPRequest) -> Option { println!("Receive request: {:?}", req);

// Return the auto-generated response
req.response

}

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:

```rust extern crate coap;

use coap::{CoAPClient, CoAPResponse};

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

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

} ```
