## What it is
quiche is Cloudflare's Rust implementation of the QUIC transport protocol and HTTP/3 as specified by the IETF. It exposes a low-level API for processing QUIC packets and managing connection state, with the application responsible for I/O and event loops.

## Use cases
- add HTTP/3 support to a server or edge network
- implement a QUIC client or server in Rust
- integrate HTTP/3 into curl
- implement DNS over HTTP/3
- experiment with the QUIC transport protocol

## When to choose
- you need a production-proven QUIC/HTTP-3 implementation (powers Cloudflare's edge)
- you want a low-level QUIC API with full control over I/O and event loops
- you're building in Rust or integrating via C FFI (e.g., curl, Android)

## When to avoid
- you need a batteries-included HTTP server with built-in socket handling
- you only need HTTP/1.1 or HTTP/2
- you want the bundled example apps for production use (they are explicitly not production-ready)

## Facets
- artifact type: library
- maturity: stable
- function: http-server, http-client, networking, security
- domain: networking, web-development, developer-tools
- platform: rust, cross-platform, windows
- tags: quic, http3, transport-protocol, tls, low-level-api, linux, macos, android
