async-coap: An experimental, asynchronous CoAP library

Introduction

rust-async-coap is an experimental, asynchronous Rust library for using and serving Constrained Application Protocol (CoAP) resources.

This library provides a flexible, asynchronous interface for using and serving CoAP resources. A back-end that wraps around Rust's standard UdpSocket is included, but can be replaced with one supporting DTLS, SMS, or whatever else you might think of.

See the crate documentation for more information.

What is CoAP?

CoAP is a RESTful application protocol (like HTTP) designed for highly embedded devices and small packet sizes. It is similar to HTTP in the sense that it is request/response based, has methods like GET/PUT/POST, and uses hierarchical URLs to identify resources; but unlike HTTP it is optimized for machine-to-machine interactions and includes mechanisms for asynchronously observing resources for changes.

CoAP is the basis for several upcoming IoT protocols.

Usage

Add this to your Cargo.toml:

[dependencies]
async-coap = "0.1.0"

Now, you can use rust-async-coap:

use async_coap::prelude::*;
