Autosar DLT Support

A library that support efficient parsing & writing log-messages encoded as Diagnositic Log and Trace messages.

Features

• compliant with the official Autosar DLT specification
• efficiently parse binary DLT content
• serialize DLT messages
• support for non-verbose messages via FIBEX file information

Usage

Add this to your Cargo.toml:

[dependencies]
dlt_core = "0.10"

This is an example of how to parse a message and serialize it back to a byte array.

use dlt_core::dlt_parse::{dlt_message, ParsedMessage};

fn main() {
    let raw1: Vec<u8> = vec![

        _ => panic!("could not parse message"),
    }
