Crate coap[−][src]
Expand description
Implementation of the [CoAP Protocol][spec].
This library provides both a client interface (CoAPClient)
and a server interface (CoAPServer).
Features:
Installation
First add this to your Cargo.toml:
[dependencies]
coap = "0.11"Then, add this to your crate root:
extern crate coap;Example
Server:
#![feature(async_closure)]
extern crate coap;
use coap_lite::{RequestType as Method};
use coap::Server;
use tokio::runtime::Runtime;
fn main() {
let addr = "127.0.0.1:5683";
Runtime::new().unwrap().block_on(async move {
let mut server = Server::new(addr).unwrap();
println!("Server up on {}", addr);
server.run(async move |request| {
match request.get_method() {
&Method::Get => println!("request by get {}", request.get_path()),
&Method::Post => println!("request by post {}", String::from_utf8(request.message.payload).unwrap()),
&Method::Put => println!("request by put {}", String::from_utf8(request.message.payload).unwrap()),
_ => println!("request by other method"),
};
return match request.response {
Some(mut message) => {
message.message.payload = b"OK".to_vec();
Some(message)
},
_ => None
};
}).await.unwrap();
});
}Client:
extern crate coap;
use coap_lite::{RequestType as Method, CoapRequest};
use coap::{CoAPClient};
fn main() {
let url = "coap://127.0.0.1:5683/Rust";
println!("Client request: {}", url);
let response = CoAPClient::get(url).unwrap();
println!("Server reply: {}", String::from_utf8(response.message.payload).unwrap());
