Packages that use ConnectionId

Package	Description
io.github.mahmoudimus.quic	A dependency-free QUIC transport (RFC 9000, 9001, 9002, 9221, 9369).
io.github.mahmoudimus.quic.connection	The sans-I/O QUIC connection and endpoint, ported from quinn-proto: the Connection state machine (handshake, packet assembly and processing, key updates, closing and draining), the Endpoint that routes datagrams and answers with Version Negotiation, Retry and stateless resets, their configurations (TransportConfig, ServerConfig, ClientConfig, EndpointConfig), and the building blocks they are made of: range sets (RangeSet), reassembly of received data (Assembler), buffering of sent data (SendBuffer), streams and flow control (StreamsState), packet number spaces and ACK generation (PacketSpace), loss detection (Recovery), pacing (Pacer), path MTU discovery (MtuDiscovery) and timers (TimerTable).
io.github.mahmoudimus.quic.crypto	QUIC packet protection (RFC 9001 section 5): AEAD payload keys, header protection keys, Initial keys per version, key updates and the Retry integrity tag.
io.github.mahmoudimus.quic.frame	QUIC frames (RFC 9000 section 19, RFC 9221 DATAGRAM, and the ACK frequency extension): a sealed Frame hierarchy, its encoders and a validating decoder.
io.github.mahmoudimus.quic.packet	QUIC packets (RFC 9000 section 17, RFC 9369): header encoding and partial decoding, packet number truncation and recovery, coalesced datagrams, and protecting and unprotecting whole packets in place.
io.github.mahmoudimus.quic.params	QUIC transport parameters (RFC 9000 section 18), carried in the TLS quic_transport_parameters extension.
io.github.mahmoudimus.quic.token	Address validation tokens (RFC 9000 section 8.1), ported from quinn-proto's token.rs and bloom_token_log.rs: Retry and NEW_TOKEN tokens sealed with AES-256-GCM under a key the server holds (TokenKey), their validation with expiry and address binding (TokenValidator), and a bounded replay log (BloomTokenLog); on the client, where NEW_TOKEN tokens wait for the next connection (TokenStore, TokenMemoryCache).
