Classes
class	rpnx::compression::deflate_codec::huffman_decoder
	Canonical Huffman decoder for the bit-reversed codes used by DEFLATE. More...
class	rpnx::compression::deflate_codec::iterator_bit_writer< output_iterator >
	LSB-first bit writer that emits bytes through an STL output iterator. More...
class	rpnx::compression::deflate_codec::iterator_bit_reader< byte_reader_type >
	LSB-first bit reader that consumes a single-pass byte reader. More...

Namespaces
namespace	rpnx::compression
	Facilities for creating and decoding supported compressed streams.
namespace	rpnx::compression::deflate_codec
	Internal implementation shared by raw DEFLATE, zlib, gzip, and ZIP.

Functions
std::uint16_t	rpnx::compression::deflate_codec::reverse_bits (std::uint16_t value, std::uint8_t bit_count) noexcept
	Reverses the selected low bits for DEFLATE wire order.
template<typename writer_type>
void	rpnx::compression::deflate_codec::write_fixed_symbol (writer_type &writer, std::uint16_t symbol)
	Emits one fixed-Huffman literal or length symbol.
std::uint32_t	rpnx::compression::deflate_codec::crc32 (std::span< std::byte const > input) noexcept
	Computes the reflected IEEE CRC-32 used by gzip and ZIP.
template<typename writer_type>
void	rpnx::compression::deflate_codec::compress_fixed_block (writer_type &writer, std::span< std::byte const > input, bool final_block, std::int32_t level)
	Emits one fixed-Huffman DEFLATE block from a bounded search buffer.
template<std::input_iterator input_iterator, std::sentinel_for< input_iterator > sentinel, typename output_iterator>
output_iterator	rpnx::compression::deflate_codec::compress (format stream_format, input_iterator first, sentinel last, output_iterator output, compression_options const &options)
	Compresses an iterator range as raw DEFLATE, zlib, or gzip.
template<std::input_iterator input_iterator, std::sentinel_for< input_iterator > sentinel, typename output_iterator>
output_iterator	rpnx::compression::deflate_codec::decompress (format stream_format, input_iterator first, sentinel last, output_iterator output, decompression_options const &options)
	Decompresses raw DEFLATE, zlib, or gzip input.
