#![cfg_attr(not(feature = "std"), no_std)]

//! Main protocol implementation.
//!
//! This crate provides the basic components in order to be able to send and receive
//! commands and events from a device.
//!
//! It is meant to be as lean as possible in order to run in restricted environments.
//! For this reason, it doesn't include any transport implementations.
