ExZstd

zstd library for Elixir, not published yet

It uses the Rust zstd binding to make cross system compilation easier (tried to do it native with the Makefile etc but I failed at making it work on windows 10 which is my main OS, the speed difference is virtually inexistent)

API so far

ExZstd.compress("your_binaries") compress the binary, default size compression to 3

ExZstd.compress("your_binaries", your_custom_compression_size) compress the binary, setting up your custom compress size

ExZstd.decompress(your_compressed_data) decompress the data

Benchmark
