lzma_next_coder lzma_stream_coder::block_decoder |
Block or Metadata decoder. This takes little memory and the same data structure can be used to decode every Block Header, so it's a good idea to have a separate lzma_next_coder structure for it.
lzma_block lzma_stream_coder::block_options |
Options for the Block encoder.
Block options decoded by the Block Header decoder and used by the Block decoder.
lzma_stream_flags lzma_stream_coder::stream_flags |
Stream Flags from Stream Header.
lzma_index_hash* lzma_stream_coder::index_hash |
Index is hashed so that it can be compared to the sizes of Blocks with O(1) memory usage.
uint64_t lzma_stream_coder::memlimit |
Memory usage limit.
uint64_t lzma_stream_coder::memusage |
Amount of memory actually needed (only an estimate)
bool lzma_stream_coder::tell_no_check |
If true, LZMA_NO_CHECK is returned if the Stream has no integrity check.
bool lzma_stream_coder::tell_unsupported_check |
If true, LZMA_UNSUPPORTED_CHECK is returned if the Stream has an integrity check that isn't supported by this liblzma build.
bool lzma_stream_coder::tell_any_check |
If true, LZMA_GET_CHECK is returned after decoding Stream Header.
bool lzma_stream_coder::ignore_check |
If true, we will tell the Block decoder to skip calculating and verifying the integrity check.
bool lzma_stream_coder::concatenated |
If true, we will decode concatenated Streams that possibly have Stream Padding between or after them. LZMA_STREAM_END is returned once the application isn't giving us any new input, and we aren't in the middle of a Stream, and possible Stream Padding is a multiple of four bytes.
bool lzma_stream_coder::first_stream |
When decoding concatenated Streams, this is true as long as we are decoding the first Stream. This is needed to avoid misleading LZMA_FORMAT_ERROR in case the later Streams don't have valid magic bytes.
size_t lzma_stream_coder::pos |
Write position in buffer[] and position in Stream Padding.
uint8_t lzma_stream_coder::buffer |
Buffer to hold Stream Header, Block Header, and Stream Footer. Block Header has biggest maximum size.
bool lzma_stream_coder::block_encoder_is_initialized |
True if Block encoder has been initialized by stream_encoder_init() or stream_encoder_update() and thus doesn't need to be initialized in stream_encode().
lzma_next_coder lzma_stream_coder::block_encoder |
Block.
lzma_filter lzma_stream_coder::filters[LZMA_FILTERS_MAX+1] |
The filter chain currently in use.
lzma_next_coder lzma_stream_coder::index_encoder |
Index encoder. This is separate from Block encoder, because this doesn't take much memory, and when encoding multiple Streams with the same encoding options we avoid reallocating memory.
lzma_index* lzma_stream_coder::index |
Index to hold sizes of the Blocks.
size_t lzma_stream_coder::buffer_pos |
Read position in buffer[].
size_t lzma_stream_coder::buffer_size |
Total number of bytes in buffer[].
