1

strategyFixed → const int

This strategy prevents the use of dynamic Huffman codes, allowing for a simpler decoder

4

strategyHuffmanOnly → const int

Use this strategy to force Huffman encoding only (no string match)

2

strategyRle → const int

Use this strategy to limit match distances to one (run-length encoding)
