Package org.lwjgl.util.zstd

@NullMarked package org.lwjgl.util.zstd

Contains bindings to Zstandard (zstd), a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios.

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set.
