Crate can_dbc

A CAN database (dbc) format parser written with Rust’s nom parser combinator library. CAN databases are used to exchange details about a CAN network. E.g. what messages are being send over the CAN bus and what data do they contain.

use can_dbc::DBC;
use codegen::Scope;

use std::fs::File;
use std::io;
use std::io::prelude::*;

fn main() -> io::Result<()> {
    let mut f = File::open("./examples/sample.dbc")?;
    let mut buffer = Vec::new();
    f.read_to_end(&mut buffer)?;

    let dbc = can_dbc::DBC::from_slice(&buffer).expect("Failed to parse dbc file");

    let mut scope = Scope::new();
    for message in dbc.messages() {
        for signal in message.signals() {

            let mut scope = Scope::new();
            let message_struct = scope.new_struct(message.message_name());
            for signal in message.signals() {
                message_struct.field(signal.name().to_lowercase().as_str(), "f64");
            }
        }
    }

    println!("{}", scope.to_string());
    Ok(())
}

Signal

One or multiple signals are the payload of a CAN frame. To determine the actual value of a signal the following fn applies: let fnvalue = |can_signal_value| -> can_signal_value * factor + offset;
