I would also like to note that I commented out all of the code in all of my files so that all of the files are literally comments. The only line of Rust Code after my outcommenting was

fn main() {}

and it still did not compile and failed with the same error, just not in utils, but rather in my main project.

Code

fn main() {
    let x = std::fs::read_to_string("setup.py");
    dump!(x);
}

Definition of dump (I think it panics there as it tells me that get_type_of() is "well formed end of query stack")

#![feature(core_intrinsics)]

pub fn get_type_of<T>(_: T) -> String {
    unsafe { std::intrinsics::type_name::<T>() }.to_owned()
}

#[macro_export]
macro_rules! dump {
    ($($a: expr),*) => {
        println!(concat!("[", file!(),":", line!(), "] ", $(stringify!($a), ": {} = {:?}; "),*), $($crate::get_type_of(&$a), $a),*);
    }
}
