quicr

quicr is an implementation of the QUIC network protocol undergoing standardization by the IETF. It is currently suitable for experimental use. The implementation is split up into the state machine crate quicr-core which performs no IO internally and can be tested deterministically, and a high-level tokio-compatible API in quicr. See quicr/examples/ for usage.

Building

Because TLS1.3 is a new standard, OpenSSL 1.1.1-pre6 (or later) is required for quicr to build. For compatibility with most other QUIC implementations as of this writing, it should be patched with openssl-tls-28.patch in this repository.
