Crate sntpc_net_tokio 

Tokio async runtime UDP socket adapter for the sntpc SNTP client library.

This crate provides a wrapper around tokio::net::UdpSocket that implements the NtpUdpSocket trait, enabling asynchronous SNTP requests using the Tokio runtime.

Design Rationale

The network adapters are separated into their own crates to:

• Enable independent versioning (updating Tokio doesn’t require updating sntpc core)
• Allow version flexibility (works with any Tokio 1.x version)
• Keep the core SNTP protocol logic independent of async runtimes
• Simplify future compatibility (only this adapter needs updating for Tokio 2.x)

Example

use sntpc::{get_time, NtpContext, StdTimestampGen};
use sntpc_net_tokio::UdpSocketWrapper;
use tokio::net::UdpSocket;

#[tokio::main]
async fn main() {
    let socket = UdpSocket::bind("0.0.0.0:0")
        .await
        .expect("Failed to bind socket");
    let socket = UdpSocketWrapper::from(socket);
    let context = NtpContext::new(StdTimestampGen::default());

    let result = get_time("pool.ntp.org:123".parse().unwrap(), &socket, context).await;
    match result {
        Ok(time) => println!("Received time: {}.{}", time.sec(), time.sec_fraction()),
        Err(e) => eprintln!("Failed to get time: {:?}", e),
    }
}
