Contract

• assert getrandom::fill accepts &mut [u8], returns Result<(), Error>, and succeeds for a non-empty buffer on the supported test target
• assert getrandom::fill_uninit accepts &mut [MaybeUninit<u8>] and returns a writable &mut [u8] with the input length
• assert getrandom::u32 and getrandom::u64 return Result<u32, Error> and Result<u64, Error> and succeed on the supported test target
• assert getrandom::fill and fill_uninit return Ok for empty slices and fill_uninit returns a zero-length slice
• assert Error::UNSUPPORTED, ERRNO_NOT_POSITIVE, and UNEXPECTED are distinct and Error::new_custom creates a distinct custom value
