Async-friendly WebTransport implementation in Rust
Pure-Rust async implementation of WebTransport over HTTP/3, covering both server and client sides. Targets real-time use cases — games, streaming, collaborative tools — where WebSocket latency or HTTP/1.1 request overhead is the bottleneck. The protocol itself is still a draft, and this library tracks it.
1. Clean split between `wtransport-proto` (protocol primitives) and `wtransport` (user-facing API) — easy to read and test in isolation. 2. The builder-pattern config API is ergonomic; the double-await server accept pattern is a bit odd but accurately models the two-phase HTTP/3 handshake rather than hiding it. 3. Tokio-native throughout, no blocking I/O, and the JS browser example works against the Rust server with no extra glue. 4. CI includes MSRV checks and a separate audit workflow — this is a library that takes semver and supply-chain hygiene seriously.
1. The WebTransport spec is still a draft; the README flags this honestly, but it means the API surface can break without being a semver violation from the maintainer's perspective. 2. 677 stars and only one language binding (Elixir) — community is thin, which matters for a networking library where you need bug reports from production deployments to shake out edge cases. 3. TLS setup for local dev requires generating a self-signed cert and trusting it manually; there's a `gencert` example but no out-of-the-box dev-friendly cert path, which creates friction for first-time setup. 4. No mention of load testing, benchmarks, or connection limits — for a library selling itself on low latency, the absence of any perf numbers is a gap.
