## What it is
TQUIC is a high-performance, lightweight, cross-platform library implementing the IETF QUIC and HTTP/3 protocols, written in Rust with APIs for Rust, C, and C++. It supports pluggable congestion control (CUBIC, BBR, BBRv3, COPA), Multipath QUIC, and includes example CLI tools.

## Use cases
- add QUIC/HTTP3 transport to a server or client application
- build a low-latency transport layer with multipath support
- experiment with congestion control algorithms like BBRv3 and COPA
- implement connection migration across changing networks
- embed a memory-safe QUIC stack in C/C++ projects
- benchmark QUIC throughput and latency

## When to choose
- you need a high-performance QUIC/HTTP3 implementation with Rust/C/C++ APIs
- you want Multipath QUIC or pluggable congestion control
- memory safety and extensive fuzz/interop testing are priorities
- you need cross-platform support including mobile platforms

## When to avoid
- you only need a full HTTP server rather than a transport library
- your stack is TCP-based and QUIC adoption is not required
- you need a QUIC implementation in a language other than Rust/C/C++
