//! Brief summary
//! * is a library for parsing M-Bus frames and user data.
//! * aims to be a modern, open source decoder for wired m-bus protocol decoder for EN 13757-2 physical and link layer, EN 13757-3 application layer of m-bus
//! * was implemented using the publicly available documentation available at <https://m-bus.com/>
//! # Example
//! ```rust
//! use m_bus_parser::frames::{ Address, Frame, Function };
//! use m_bus_parser::user_data::{ DataRecords, UserDataBlock };
//! use m_bus_parser::mbus_data::MbusData;
//! use std::io;
//!
//!     let example = vec![
