[](https://crates.io/crates/quiche) [](https://docs.rs/quiche) [](https://opensource.org/licenses/BSD-2-Clause) [quiche] is an implementation of the QUIC transport protocol and HTTP/3 as specified by the [IETF]. It provides a low level API for processing QUIC packets and handling connection state. The application is responsible for providing I/O (e.g. sockets handling) as well as an event loop with support for timers. For more information on how quiche came about and some insights into its design you can read a [post] on Cloudflare's blog that goes into some more detail. quiche powers Cloudflare edge network's HTTP/3 support. The cloudflare-quic.com website can be used for testing and experimentation. Android's DNS resolver uses quiche to implement DNS over HTTP/3. quiche can be integrated into curl to provide support for HTTP/3. Before diving into the quiche API, here are a few examples on how to use the quiche tools provided as part of the quiche-apps crate. These are not suitable for production…
