module lwjgl.lz4

Package org.lwjgl.util.lz4

Annotations
@NonnullDefault
Contains bindings to LZ4, a lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. It features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
