Filter ID. This is LZMA_VLI_UNKNOWN when this structure doesn't point to a filter coder.

| uintptr_t lzma_next_coder_s::init |
"Pointer" to init function. This is never called here. We need only to detect if we are initializing a coder that was allocated earlier. See lzma_next_coder_init and lzma_next_strm_init macros in this file.

Pointer to function to do the actual coding.

Pointer to function to free lzma_next_coder.coder. This can be NULL; in that case, lzma_free is called to free lzma_next_coder.coder.

| lzma_check(* lzma_next_coder_s::get_check)(const lzma_coder *coder) |
Pointer to function to return the type of the integrity check. Most coders won't support this.
| lzma_ret(* lzma_next_coder_s::memconfig)(lzma_coder *coder, uint64_t *memusage, uint64_t *old_memlimit, uint64_t new_memlimit) |
Pointer to function to get and/or change the memory usage limit. If new_memlimit == 0, the limit is not changed.

| lzma_ret(* lzma_next_coder_s::update)(lzma_coder *coder, lzma_allocator *allocator, const lzma_filter *filters, const lzma_filter *reversed_filters) |
Update the filter-specific options or the whole filter chain in the encoder.
