    )

This module compresses the input file read from input stream. It produces the ZSTD compressed data at the output stream.

Parameters:

BLOCK_SIZE ZStd block size
LZWINDOW_SIZE LZ77 history size or Window size
MIN_BLCK_SIZE Minimum block size, less than that will be considered stored block
PARALLEL_HUFFMAN Number of Huffman encoding units used
PARALLEL_LIT_STREAMS Number of parallel literal streams encoded using huffman
MIN_MATCH Minimum match in LZ77
inStream input stream
outStream output stream
