Module bitstream 

Bit-aligned reader and writer.

Per spec §4.6: bits are packed MSB-first into bytes. The first bit of the payload occupies the most-significant bit of the first byte. The final byte is zero-padded if needed.

Structs

BitReader

MSB-first bit unpacker over a borrowed byte slice.

BitWriter

MSB-first bit packer.

Functions

re_emit_bits

Reads exactly bit_len MSB-first bits from src_bytes and appends them to dst. Bits are sourced as if src_bytes were the output of a BitWriter finalized with into_bytes() (so the trailing partial byte is in the high bits of the last source byte). The destination is extended in-place — no padding inserted.
