Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol, with a high-level tokio-based API plus a sans-I/O protocol state machine. It supports client/server operation, streams, datagrams, and pluggable cryptography via rustls.

Use cases

• implement a QUIC server or client in Rust
• build an HTTP/3 transport layer
• replace TCP with a low-latency encrypted transport
• embed QUIC in a custom event loop via a sans-I/O state machine
• send small unreliable messages alongside reliable streams

When to choose

• you need a mature, pure-Rust QUIC stack with an async API
• you want pluggable cryptography and stable-Rust compatibility
• you need both reliable streams and unreliable datagrams over one connection

When to avoid

• you need a C or C++ QUIC library
• your project is not Rust-based
• you only need simple TCP/HTTP without QUIC's benefits
