Crate simoom_quic 

Sans-io QUIC v1 transport (RFC 9000, RFC 9001, RFC 9002) for simoom, with QUIC v2 (RFC 9369) when enabled in Config::versions.

The crate never touches sockets or clocks: an Endpoint takes datagrams, the time and the peer address, and returns datagrams to send, a deadline and per-connection events. Packet protection and the TLS handshake go through the crypto traits.

Modules

coding

Variable-length integers (RFC 9000 §16) and a bounds-checked reader.

config

Endpoint and transport configuration.

connection

The QUIC connection state machine (RFC 9000, RFC 9001, RFC 9002), sans-io.

crypto

The crypto boundary between the transport and TLS (RFC 9001).

endpoint

An endpoint: routes datagrams to connections by connection ID, creates server connections, and answers statelessly (Version Negotiation, Retry, stateless reset). It also keeps one deadline heap for all its connections.

error

Transport error codes (RFC 9000 §20).

frame

QUIC frames (RFC 9000 §19): zero-copy parsing and encoding.

packet

Packet headers, packet numbers, header protection, Version Negotiation, Retry and stateless reset (RFC 9000 §17, RFC 9001 §5).

params

Transport parameters (RFC 9000 §18): encoding, decoding and validation.

ranges

A set of disjoint half-open u64 ranges, kept sorted. Used for ACK ranges, received packet numbers and stream retransmission bookkeeping.

recovery

Loss detection, PTO and congestion control (RFC 9002), with a token-bucket pacer.

sim

A deterministic in-memory network for tests and benchmarks: two endpoints joined by links that can drop, duplicate, reorder and delay datagrams, with an optional bottleneck (bandwidth and queue). Time is virtual and advanced by the simulation.

stream

Streams (RFC 9000 §2–4): send and receive buffers, stream and connection flow control, stream limits, STOP_SENDING and RESET_STREAM.

tls

The production CryptoProvider: TLS 1.3 from simoom_tls::quic (RFC 9001), with AES-GCM or ChaCha20-Poly1305 packet protection, the Retry integrity tag, HMAC-SHA256 for tokens and the TLS crate’s DRBG for randomness.

token

Address-validation tokens for Retry and NEW_TOKEN (RFC 9000 §8.1), authenticated with HMAC-SHA256 under the endpoint’s token key.

vn

Compatible version negotiation (RFC 9368) between QUIC v1 and v2 (RFC 9369).
