Diagnostics over Internet Protocol (DoIP) Codec

The doip-codec crate provides a Encoder and Decoder implementation for encoding and decoding Diagnostics Over Internet Protocol (DoIP) messages. It is designed to integrate seamlessly with the Tokio ecosystem, leveraging tokio-util's Framed for efficient stream-based reading and writing of DoIP messages.

Features

• Full support for encoding and decoding DoIP messages as per the ISO 13400 standard.
• Easy integration with Tokio's asynchronous I/O framework.
• Robust and efficient handling of DoIP message framing.
• Customizable for various DoIP use cases, including vehicle diagnostics and testing.

Installation

Add the following to your Cargo.toml:

[dependencies]
doip-codec = "1.0.0"

Then, include the crate in your code:

use doip_codec::DoipCodec;

Usage

Here's a simple example to get started with DoipCodec:

use futures::{SinkExt, StreamExt};
use tokio::net::TcpStream;
use tokio_util::codec::Framed;
use doip_definitions::{
    header::DoipVersion,
    message::{DoipMessage, VehicleIdentificationRequest},
};
use doip_codec::DoipCodec;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
  // Connect to a DoIP server
  let stream = TcpStream::connect("127.0.0.1:13400").await?;

  // Wrap the stream with the DoipCodec
  let mut framed = Framed::new(stream, DoipCodec);

  // Send a DoIP message
  let request = DoipMessage::new(
      DoipVersion::Iso13400_2012,
      Box::new(VehicleIdentificationRequest {}),
  ); // Example payload

  framed.send(request).await?;

  // Receive a DoIP message
  if let Some(response) = framed.next().await {
      match response {
          Ok(msg) => println!("Received message: {:?}", msg),
          Err(e) => eprintln!("Failed to decode message: {}", e),
      }
  }

  Ok(())
}

Why DoIP?

Diagnostics Over Internet Protocol (DoIP) is a modern diagnostic communication protocol that leverages IP-based networks for vehicle diagnostics, making it a critical component in automotive software. The doip-codec crate simplifies the implementation of DoIP messaging for Rust developers.
