It's more of "yeah it worked, but I had to do a lot of hand-holding" and "it passes the tests but I cannot tell if the code has memory leaks".

Actually, I can tell; I ran split on the C source and got things like this:

disk_space.c:144:16: Only storage bin.ref_bin (type void *) derived from variable declared in this scope is not released (memory leak)

So I'm looking into a Rust version with Rustler now.

I'd also recommend having a look at the Zig library for Elixir. For simple stuff, you can just inline, but support for pretty complex setups too.

Also comes with a built-in BEAM allocator so the runtime properly reports NIF memory consumption.

Thanks, one day I'll look into Zig too, because I've been impressed with what Tigerbeetle has achieved with it! For now, I'm all-in on Elixir.
