Crate can_dbc[−][src]

Expand description

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(())
}

Structs

AttrDefault

Baudrate

Baudrate of network in kbit/s

DBC

EnvironmentVariable

EnvironmentVariableData

Message

CAN message (frame) details including signal details

MessageId

CAN id in header of CAN frame. Must be unique in DBC file.

MessageTransmitter

Node

CAN network nodes, names must be unique

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;

SignalExtendedValueTypeList

SignalGroups

Signal groups define a group of signals within a message

Global value table

This error type accumulates errors and their position when backtracking through a parse tree. With some post processing (cf examples/json.rs), it can be used to display user friendly error messages
