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.
you can use zigler for a c nif, using easy_c (or c_src) options.
the big advantage is that it will automatically box/unbox to/from c values for you and generate sane error messages (which rustler does not, last i checked) when you pass incompatible terms in to the function.
on the other hand rustler lets you precompile (which is coming in a future version of Zigler)
