WTransport - WebTransport library in Rust 🦀

WebTransport is a modern update to Websockets, transmitting data between client and server using http3.

WTransport is an implementation http3 WebTransport written in Rust.

Async-friendly WebTransport implementation in Rust

WTransport

WebTransport protocol, pure-rust, async-friendly.

Introduction

WebTransport is a new protocol being developed to enable low-latency, bidirectional communication between clients and servers over the web It aims to address the limitations of existing protocols like HTTP and WebSocket by offering a more efficient and flexible transport layer.

Benefits of WebTransport

• 🚀 Low latency: WebTransport is designed to minimize latency, making it suitable for real-time applications such as gaming, video streaming, and collaborative editing.
• 🔄 Bidirectional communication: WebTransport allows simultaneous data exchange between the client and server, enabling efficient back-and-forth communication without the need for multiple requests.
• 🔀 Multiplexing: With WebTransport, multiple streams can be multiplexed over a single connection, reducing overhead and improving performance.
• 🔒 Security: WebTransport benefits from the security features provided by the web platform, including transport encryption and same-origin policy.

WTransport's simple API

WTransport comes with both server and client implementaton. Here is how it looks:

Server

#[tokio::main]
async fn main() -> Result<()> {
    let config = ServerConfig::builder()
        .with_bind_default(4433)
        .with_certificate(certificate)
        .build();

    let connection = Endpoint::server(config)?
        .accept()
        .await     // Awaits connection
        .await?    // Awaits session request
        .accept()  // Accepts request
        .await?;   // Awaits ready session

    let stream = connection.accept_bi().await?;
    // ...
}

Client

#[tokio::main]
async fn main() -> Result<()> {
    let config = ClientConfig::default();

    let connection = Endpoint::client(config)?
        .connect("https://[::1]:4433")
        .await?;

    let stream = connection.open_bi().await?.await?;
    // ...
}

Get Started

The repo has a full example, where you launch a server and a chrome instance to communicate with each other over h3 WebTransport protocol. Here you can find it:
