Implementations

impl DraftVersion

pub fn version_varint(&self) -> VarInt

The MoQT version number announced in CLIENT_SETUP.

Format: 0xff000000 + draft_number. Draft-15+ use ALPN for version negotiation and may not include a version in CLIENT_SETUP at all.

pub fn quic_alpn(&self) -> &'static [u8]

The ALPN protocol identifier for raw QUIC connections.

Drafts 07–14 all use moq-00 and negotiate the draft version in CLIENT_SETUP / SERVER_SETUP. Draft-15+ encode the draft number in the ALPN itself (moqt-<N>), per §3.1.2 of each spec.

pub fn from_alpn(alpn: &[u8]) -> Option<DraftVersion>

Resolve an ALPN identifier to a specific draft version.

Returns Some for ALPNs that unambiguously identify a draft (moqt-15, moqt-16, moqt-17, moqt-18). Returns None for moq-00 — which covers drafts 07–14 and requires inspecting CLIENT_SETUP’s supported-versions list — and for any unrecognized ALPN.

pub fn from_number(n: u8) -> Option<DraftVersion>

Resolve a draft number (e.g. 7..=18) to a DraftVersion.

Returns None for numbers outside the supported range.

pub fn uses_fixed_length_framing(&self) -> bool

Whether this draft uses a 16-bit big-endian message length in control message framing (true) or a QUIC varint (false).

Draft-11 changed the framing from Length(i) to Length(16).

pub fn number(&self) -> u8

The draft number (e.g. 7, 14, 17).

Trait Implementations

impl Clone for DraftVersion

fn clone(&self) -> DraftVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DraftVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DraftVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for DraftVersion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DraftVersion

fn eq(&self, other: &DraftVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
