Module compression 

Compression algorithms for save data: RLE, LZ4-style, Huffman, and delta encoding.

Compressor::compress_auto tries every algorithm and picks the smallest output, storing the result in a self-describing CompressedBlock.

Structs

CompressedBlock

A self-describing compressed block.

Compressor

High-level compressor: tries every algorithm and picks the smallest result.

DeltaDecoder

Delta decoder.

DeltaEncoder

Delta-encode sorted integer arrays then apply RLE on the deltas.

HuffmanDecoder

Canonical Huffman decoder.

HuffmanEncoder

Canonical Huffman encoder.

Lz4Decoder

LZ4-style block decompressor.

Lz4Encoder

LZ4-style block compressor using a 4-byte hash chain.

RunLengthEncoder

Byte-level run-length encoding.

Enums

CompressionAlgorithm

Which compression algorithm was used to produce a CompressedBlock.
