`gzip_crc32`	Compute CRC-32 of buffer.
`_gz_write16`	Internal: write little-endian 16-bit value.
`_gz_write32`	Internal: write little-endian 32-bit value.
`_gz_read32`	Internal: read little-endian 32-bit value.
`gzip_compress`	Compress data with gzip stored-block format. Returns output length.
`gzip_is_gzip`	Check if buffer starts with gzip magic bytes.
`gzip_orig_size`	Read original size from gzip trailer (last 4 bytes).
`gzip_decompress`	Decompress gzip stored-block data. Returns output length.

fn _gz_byte_at(buf: &i8, idx: i64) -> i64

Internal byte reader.

fn _gz_crc32_byte(crc: i64, byte_val: i64) -> i64

CRC-32 table (precomputed for polynomial 0xEDB88320). We compute it on-the-fly per byte.

fn gzip_crc32(buf: &i8, len: i64) -> i64

Compute CRC-32 of buffer.

fn _gz_write16(out: &i8, pos: i64, val: i64) -> i64

Internal: write little-endian 16-bit value.

fn _gz_write32(out: &i8, pos: i64, val: i64) -> i64

Internal: write little-endian 32-bit value.

fn _gz_read32(buf: &i8, pos: i64) -> i64

Internal: read little-endian 32-bit value.

fn gzip_compress(input: &i8, in_len: i64, out: &i8) -> i64

Compress data with gzip stored-block format. Returns output length.

fn gzip_is_gzip(buf: &i8, len: i64) -> i64

Check if buffer starts with gzip magic bytes.

fn gzip_orig_size(buf: &i8, len: i64) -> i64

Read original size from gzip trailer (last 4 bytes).

fn gzip_decompress(input: &i8, in_len: i64, out: &i8) -> i64

Decompress gzip stored-block data. Returns output length.
