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 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

use m_bus_parser::frames::{ Address, Frame, Function };
use m_bus_parser::user_data::{ DataRecords, UserDataBlock };
use std::io;

    let example = vec![
        0x68, 0x4D, 0x4D, 0x68, 0x08, 0x01, 0x72, 0x01,

        0x00, 0x00, 0x00, 0x0C, 0x78, 0x56, 0x00, 0x00,
        0x00, 0x01, 0xFD, 0x1B, 0x00, 0x02, 0xFC, 0x03,
        0x48, 0x52, 0x25, 0x74, 0x44, 0x0D, 0x22, 0xFC,

        0x1F, 0xB3, 0x16
    ];

    // Parse the frame
    let frame = Frame::try_from(example.as_slice()).unwrap();

    if let Frame::LongFrame { function, address, data } = frame {
        assert_eq!(function, Function::RspUd { acd: false, dfc: false });
        assert_eq!(address, Address::Primary(1));
        if let Ok(UserDataBlock::VariableDataStructure { fixed_data_header, variable_data_block }) = UserDataBlock::try_from(data) {
            let data_records = DataRecords::try_from(variable_data_block).unwrap();
            println!("data_records: {:#?}", data_records);
            let data_records = DataRecords::try_from(variable_data_block).unwrap();
        }
    }

    // Parse everything at once
    let parsed_data = m_bus_parser::MbusData::try_from(example.as_slice()).unwrap();
    println!("parsed_data: {:#?}", parsed_data);
