noq #

General purpose implementation of the QUIC transport protocol in pure Rust. Noq is built as an async-friendly API in the noq crate on top of a sans-io protocol library in noq-proto.

Noq started out as a fork of the excellent Quinn project. The main focus of development has been towards adding support for more QUIC (draft) extensions:

• QUIC Multipath
• QUIC Address Discovery (QAD)
• Using QUIC to traverse Nat's (QNT)

Features #

• Easy to use futures-based async API.
• Client and server server functionality.
• 0-RTT and 0.5-RTT data support.
• Ordered and unordered stream reads.
• Custom and zero-length connection identifiers.
• Fully pluggable crypto API with a Rustls implementation using ring or aws-lc-rs provided by default for convenience.
• Broad platform support, including Linux, Windows, macOS, android, iOS and wasm.

Standards #

The noq library aims to be correct implementation of various QUIC standards:

• Supports the core QUIC specifications:
  • RFC 8999 - Version-Independent Properties of QUIC.
  • RFC 9000 - QUIC: A UDP-Based Multiplexed and Secure Transport.
  • RFC 9001 - Using TLS to Secure QUIC.
  • RFC 9002 - QUIC Loss Detection and Congestion Control.
• The standardised QUIC extensions:
  • RFC 9221 - An Unreliable Datagram Extension to QUIC.
  • RFC 9287 - Greasing the QUIC Bit.
  • RFC 9368 - Compatible Version Negotiation for QUIC.
• Draft extensions:
  • qlog: Structured Logging for Network Protocols.
  • QUIC Multipath.
    • With experimental qlog support.
  • QUIC Address Discovery (QAD).
  • Using QUIC to traverse NATs (QNT).

Getting started #

Examples at https://github.com/n0-computer/noq/blob/main/noq/examples

$ cargo run --example server ./
$ cargo run --example client https://localhost:4433/Cargo.toml

This launches an HTTP 0.9 server over the QUIC transport on the loopback address serving the current working directory, with the client fetching ./Cargo.toml. By default, the server generates a self-signed certificate and stores it to disk, where the client will automatically find and trust it.
