Struct BdwHeader 

pub struct BdwHeader { /* private fields */ }

Parsed BDW header (block length + reserved).

A 4-byte Block Descriptor Word containing a 2-byte big-endian block length that includes these 4 header bytes, plus 2 reserved bytes that must be zero.

Implementations

impl BdwHeader

pub const fn from_bytes(bytes: [u8; 4]) -> BdwHeader

Construct from raw 4-byte header bytes.

pub fn from_block_len(block_len: usize) -> Result<BdwHeader, Error>

Construct from a block length, validating the 0.7 wire bounds.

Errors

Returns CBKF222_BDW_LENGTH_INVALID when block_len is below the header size or above the 32760-byte maximum.

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

Return raw bytes.

pub const fn length(self) -> u16

Extract block length, BDW header included.

pub const fn reserved(self) -> u16

Extract reserved bytes.
