A fast and stable Constrained Application Protocol(CoAP) library implemented in Rust.
First add this to your Cargo.toml
:
[dependencies]
coap = "0.5"
Then, add this to your crate root:
extern crate coap;
extern crate coap;
use std::io;
use coap::{CoAPServer, CoAPResponse, CoAPRequest};
fn request_handler(req: CoAPRequest) -> Option<CoAPResponse> {
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");
}
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());
}
