Struct Version 

pub struct Version(/* private fields */);

Available on crate feature quic only.

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

Implementations

impl Version

pub const V1: Version

QUIC version 1 (RFC 9000).

pub const V2: Version

QUIC version 2 (RFC 9369).

pub const fn from_u32(version: u32) -> Version

A version from its 32-bit wire value.

pub const fn as_u32(self) -> u32

The 32-bit wire value.

pub const fn to_be_bytes(self) -> [u8; 4]

The version in network byte order.

pub const fn from_be_bytes(bytes: [u8; 4]) -> Version

A version from network byte order.

pub const fn is_negotiation(self) -> bool

Zero, which marks a Version Negotiation packet rather than a version (RFC 8999 §6).

pub const fn is_reserved(self) -> bool

Whether this is one of the 0x?a?a?a?a versions reserved to exercise version negotiation (RFC 9000 §15). Such a version is never selected.

pub const fn is_standard(self) -> bool

Whether this is a standardized version this crate implements.

pub const fn is_compatible_with(self, other: Version) -> bool

Whether a first flight in this version can be converted into one of other (RFC 9368 §2.2). Version 1 and version 2 are compatible in both directions (RFC 9369 §4); a version is always compatible with itself.

pub const fn grease(avoid: Version) -> Version

A reserved version to grease a version list with, distinct from avoid.

pub const fn wire(self) -> Option<&'static Wire>

The version-specific wire constants, when this crate implements the version.

pub const fn to_wire(self) -> Option<WireVersion>

This version as a WireVersion, when this crate implements it.

This is the one place the “is this version implemented?” question is answered; a WireVersion then carries the proof, so every wire operation on it is infallible.
