Crate proto 

Available on crate feature quic only.

QUIC wire types, codec, version vocabulary and profiles for Rama.

This crate is the deterministic protocol layer beneath rama-quic: the packet and frame codec, the version wire tables and negotiation vocabulary, and the typed, invariant-checked profiles describing a client’s observable wire image. It has no connection state machine and no async runtime, so tools that only need to read or describe QUIC on the wire — user-agent emulation, fingerprinting, packet analysis — can depend on it without pulling in the engine.

Rama

Crate used by the end-user rama crate and rama crate authors alike.

Modules

capturestd

Reading a first flight back from the wire: what any observer sees, and what one that can open the Initial packets sees.

coding

Coding related traits.

constant_time

crypto

Packet-protection key interfaces (RFC 9001 §5).

frame

packet

profile

Typed, invariant-preserving QUIC wire profiles.

range_set

transport_parameters

QUIC connection transport parameters

version

QUIC protocol versions and the wire constants that differ between them.

Structs

ConnectionId

Protocol-level identifier for a connection.

InvalidCid

connection ID was not recognized by the connection ID generator

ResetToken

Stateless reset token used to securely communicate that an endpoint has lost state for a connection (RFC 9000 §10.3).

StreamId

Identifier for a stream within a particular connection.

TransportError

Transport-level errors occur when a peer violates the protocol specification

TransportErrorCode

Transport-level error code

VarInt

An integer less than 2^62

VarIntBoundsExceeded

Error returned when constructing a VarInt from a value >= 2^62. value too large for varint encoding

VarIntDecoder

Incremental, fragmentation-safe decoder for a single QUIC variable-length integer.

Version

A QUIC version number as it appears in long headers (RFC 8999 §5).

Enums

Dir

Whether a stream communicates data in both directions or only from the initiator.

EcnCodepoint

Explicit congestion notification codepoint.

Side

Whether an endpoint was the initiator of a connection.

Constants

MAX_CID_SIZE

The longest connection ID QUIC version 1 carries, in bytes (RFC 9000 §17.2).

MAX_STREAM_COUNT

Maximum number of streams that can be uniquely identified by a stream ID (RFC 9000 §2.1).

RESET_TOKEN_SIZE

The longest stateless reset token, in bytes (RFC 9000 §10.3).
