Module profile 

Available on crate feature quic only.

Typed, invariant-preserving QUIC wire profiles.

A QuicProfile describes the parts of a connection’s wire image that an implementation is free to choose: which versions it offers, how it lays out its transport parameters, how long its connection IDs are, how large and how many its Initial datagrams are, and how frames are arranged inside them. Every knob is checked when it is set, so a profile can reproduce another implementation’s first flight but never an invalid one; there is no raw byte hook.

QuicProfile::standard() is what this crate does on its own. The browser profiles were taken from captures of the named browser versions and are verified against those captures in this crate’s tests; crate::capture is the parser that reads a first flight back.

Structs

ConnectionIdProfile

Connection ID lengths.

OpaqueParameter

A transport parameter this crate does not interpret, written as given.

PacketizationProfile

How packets and datagrams are formed.

ParameterId

The identifier of a transport parameter (RFC 9000 §18.2 and the QUIC transport parameter registry), including ones this crate does not otherwise know.

QuicProfile

A complete wire profile; see the module documentation.

TransportLimits

The advertised flow-control and timing limits, as the transport parameters carry them.

TransportParameterProfile

How the transport parameters are laid out.

Enums

GreaseParameter

The reserved parameter written to exercise the peer’s tolerance (RFC 9000 §18.1).

InitialFlightLayout

How the frames of a client’s Initial packets are arranged.

PacketNumberLength

How long packet numbers are encoded.

PaddingPlacement

Where the bytes that bring an Initial datagram up to size go.

ParameterOrder

The order transport parameters are written in.

ProfileError

A value this profile cannot hold.
