How does this work?

It use gmod-lzma-rs and make it available for Garry's Mod with threading

Lua Function

async_compress("Data to compress", function(compressed)
	print(compressed)
end)

async_decompress("Data to decompress", function(decompressed)
	print(decompressed)
end)

For Linux 32 bit, you need to do this in 2 stages:

Create a Docker image - docker build -t rust_32bit .
Execute the compilation - docker run -it -v $(pwd):/compile_area -w "/compile_area" rust_32bit
You can find the result in target/i686-unknown-linux-gnu/release/libgmsv_async_compress.so which you should copy to lua/bin/gmsv_async_compress_linux.dll
Invoke the module via require("async_compress")
