had the same thought at first, but the `BitOr` traits (and i guess all traits) are not
const, so we can't directly to this here.
what would be possible is this:
---
pub(crate) const DIR_FLAGS: OFlag =
OFlag::from_bits_truncate(OFlag::O_DIRECTORY.bits() | OFlag::O_CLOEXEC.bits());
---
which is IMHO even uglier than using `.union()` ...
