Crate m_bus_parser

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 portocol decoder for EN 13757-2 physical and link layer, EN 13757-3 application layer of m-bus
• was implemented using the publicily available documentation available at https://m-bus.com/

use m_bus_parser::frames::{ Address, Frame, Function};

let example = vec![
