= note: different `fn` items always have unique types, even if their signatures are the same
= help: change the expected type to be function pointer `extern "rust-intrinsic" fn(bool) -> bool`
= help: if the expected type is due to type inference, cast the expected `fn` to a function pointer: `likely as extern "rust-intrinsic" fn(bool) -> bool`
error: aborting due to 3 previous errors
