Expand description

Robust, ergonomic CoAP server in Rust.

Examples

use std::net::SocketAddr;

use coap_server::app::{CoapError, Request, Response};
use coap_server::{app, CoapServer, FatalServerError, UdpTransport};

#[tokio::main]
async fn main() -> Result<(), FatalServerError> {
    let server = CoapServer::bind(UdpTransport::new("0.0.0.0:5683")).await?;
    server.serve(
        app::new().resource(
            app::resource("/hello").get(handle_get_hello))
    ).await
}

async fn handle_get_hello(request: Request<SocketAddr>) -> Result<Response, CoapError> {
    let whom = request
        .unmatched_path
        .first()
        .cloned()
        .unwrap_or_else(|| "world".to_string());

    let mut response = request.new_response();
    response.message.payload = format!("Hello, {whom}").into_bytes();
    Ok(response)
}
