Struct BackwardBitWriter 

pub struct BackwardBitWriter { /* private fields */ }

Backward bitstream writer matching C zstd’s BIT_CStream_t.

Bits accumulate LSB-first in a 64-bit container. flush_bits() writes complete bytes to the output buffer in LE order. The decoder reads from the END of this buffer (BitReaderReversed).

Key: bytes are written FORWARD. No reverse needed. The decoder naturally reads backward from the last byte.

Implementations

impl BackwardBitWriter

pub fn new() -> Self

pub fn add_bits(&mut self, value: u64, nbits: u32)

Add nbits from the low bits of value to the container. Matches: BIT_addBits(bitC, value, nbBits)

pub fn flush_bits(&mut self)

Flush complete bytes from the container to the output. Matches: BIT_flushBits(bitC)

pub fn finish(self) -> Vec<u8>

Finalize: add sentinel 1-bit, flush remaining. Matches: BIT_closeCStream(bitC)

Trait Implementations

impl Default for BackwardBitWriter

fn default() -> Self

Returns the “default value” for a type.
