Is there a way that I can use `mmap` on Darwin with superpages in Rust?

The mmap manpage on Darwin specifies that in order to use mmap with superpages (the Darwin equivalent of Linux's huge pages), the VM_FLAGS_SUPERPAGE_SIZE_* flags should be used.

I'm trying to use this functionality in Rust, but I can't find these constants in either of the Rust libc versions for Darwin (i686, x86_64).

It's most likely that no one else has needed those flags yet. I'd advocate just submitting a PR to the libc crate. – Shepmaster Aug 19 '17 at 21:52
