Provides transcoding codecs for compression and decompression with LZ4. Source: LZ4 The compression algorithm is similar to the compression available through Blosc.jl, but uses the LZ4 Frame format as opposed to the standard LZ4 or LZ4_HC formats.
Codecs for the standard LZ4 and LZ4_HC formats are also provided as LZ4FastCompressor and LZ4HCCompressor. These codecs follow the LZ4 streaming examples, breaking the data into blocks and prepending each compressed block with a size. Data compressed with these codecs can be decompressed with LZ4SafeDecompressor.
Caution
LZ4FastCompressor and LZ4HCCompressor output is not compatible with lz4frame and is platform dependent.
Non-streaming functions are included via lz4_compress, lz4_hc_compress, and lz4_decompress. These should work with most other standard lz4 implementations.
