Fatal error: 'stdint.h' file not found, building argonautica rust

Setting up a backend for a site, and I wanted to use argonautica to hash. Had some problems first getting libclang.lib but after figuring out that I am now stuck on stdint.h file not found

When running nix-index, stdint.h is supposed to be inc in llvmPackages and clang?

Error when trying to compile
My flake that is used for this project

Appreciate any help!
