Struct Header 

pub struct Header {
    pub version: u8,
    pub divergent_paths: bool,
}

5-bit single-payload header per SPEC v0.30 §2.1.

Fields

version: u8

Wire-format generation (4 bits). v0.30 = 4.

divergent_paths: bool

Bit 4: false = shared origin path, true = divergent per-@N paths.

Implementations

impl Header

pub const WF_REDESIGN_VERSION: u8 = 4

Wire-format version constant for v0.30 (the redesign cycle). Usable WF-redesign version set per SPEC §2.4: {4, 8, 12}.

pub fn write(&self, w: &mut BitWriter)

Encode the 5-bit header into the bit stream.

pub fn read(r: &mut BitReader<'_>) -> Result<Self, Error>

Decode the 5-bit header from the bit stream. Rejects inputs whose version field ≠ WF_REDESIGN_VERSION (4 in this release) with Error::WireVersionMismatch per SPEC §2.5.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl PartialEq for Header

fn eq(&self, other: &Header) -> 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.
