The point is that nix-rs doesn't let you kill all the processes by accident, you have to be trying to do it in Rust. You also have to explicitly ignore the error. Whereas in C it's pretty easy to forget to check for the error and subsequently crash everything.
Sure, you can have the same higher level API in C. Though Rust will not compile if there's no exhaustive match, and you cannot access the `int ret` if it's in the wrong state, but it's close enough.
