Rust FFI is not nearly as simple as Nim's interface to C where you pretty much just call C functions.

  That's exactly Rust's FFI.

    In its most basic form, yes, but because of Rust's safety guarantees it's not quite that simple. C functions can only be called from unsafe blocks and there is a lot to be desired when you have to pass strings back and forth (I don't know how well Nim handles this). It's also a bit harder to debug an FFI wrapper in Rust when you tell the compiler your code is safe but then make a mistake in how you use the unsafe C api. I strongly prefer Rust's safety but it's not quite the same as a blind FFI like Nim.
