//! Implementation of the [CoAP Protocol][spec].
//!
//! This library provides both a client interface (`CoAPClient`)
//! and a server interface (`CoAPServer`).
//!
//! [spec]: https://tools.ietf.org/html/rfc7252
//!
//! # Installation
//!
//! First add this to your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! coap = "0.5"
//! ```
//!
//! Then, add this to your crate root:
//!
//! ```
//! extern crate coap;
//! ```
//!
//! # Example
//!
//! ## Server:
//! ```no_run
//! extern crate coap;
//! use std::io;
//! use coap::{CoAPServer, CoAPClient, CoAPRequest, CoAPResponse};
//! fn request_handler(request: CoAPRequest) -> Option<CoAPResponse> {
//! println!("Receive request: {:?}", request);
//!
//! // Return the auto-generated response
//! request.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:
//! ```no_run
//! extern crate coap;
//!
//! use coap::message::response::CoAPResponse;
//! use coap::CoAPClient;
//!
//! 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());
//! }
//! ```
