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

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

Notes

Please be aware that WebTransport is still a draft and not yet standardized. The WTransport library, while functional, is not considered completely production-ready. It should be used with caution and may undergo changes as the WebTransport specification evolves.

Simple API

#[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?;
    // ...
}

#[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?;
    // ...
}

Getting Started

Clone the Repository

git clone https://github.com/BiagioFesta/wtransport.git

cd wtransport/

Run Full Example

The examples/full.rs is a minimal but complete server example that demonstrates the usage of WebTransport.

You can run this example using Cargo, Rust's package manager, with the following command:

cargo run --example full

This example initiates an echo WebTransport server that can receive messages. It also includes an integrated HTTP server.
