Struct ChunkHeader 

pub struct ChunkHeader {
    pub version: u8,
    pub chunk_set_id: u32,
    pub count: u8,
    pub index: u8,
}

Wire header for a single chunk in a chunked v0.30 payload.

Fields

version: u8

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

chunk_set_id: u32

20-bit chunk-set identifier shared by all chunks in a set.

count: u8

Total number of chunks in the set; valid range 1..=64.

index: u8

Zero-based index of this chunk within the set; must be < count.

Implementations

impl ChunkHeader

pub fn write(&self, w: &mut BitWriter) -> Result<(), Error>

Encode the chunk header into w as 37 bits.

Returns an error if count, index, or chunk_set_id are out of range.

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

Decode a chunk header (37 bits) from r.

Returns Error::WireVersionMismatch if the 4-bit version field is not WF_REDESIGN_VERSION per SPEC §2.5 (e.g., v0.x chunked payloads where version=0 in the first 3 wire bits become version=0 or version=1 under the v0.30 4-bit read depending on prior bits). Returns Error::ChunkHeaderChunkedFlagMissing if the chunked-flag bit is not set after the version check passes.

Trait Implementations

impl Clone for ChunkHeader

fn clone(&self) -> ChunkHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkHeader

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

Formats the value using the given formatter.

impl PartialEq for ChunkHeader

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