Autosar DLT Support
A library that support efficient parsing & writing log-messages encoded as Diagnositic Log and Trace messages.
Usage
Add this to your Cargo.toml:
toml
[dependencies]
dlt_core = "0.9"
This is an example of how to parse a message and serialize it back to a byte array.
```rust
use dltcore::dltparse::{dlt_message, ParsedMessage};
fn main() {
let raw1: Vec = vec![
// --------------- storage header

match dltmessage(&raw1[..], None, true) {
Ok((rest, ParsedMessage::Item(msg))) => {

asserteq!(raw1, msgbytes);
}

}
}
```
