Struct rustix::backend::reg::ArgReg

#[repr(transparent)]
pub(super) struct ArgReg<'a, Num: ArgNumber> {
    raw: *mut Opaque,
    _phantom: PhantomData<(&'a (), Num)>,
}

Syscall arguments use register-sized types. We use a newtype to discourage accidental misuse of the raw integer values.

This type doesn’t implement Clone or Copy; it should be used exactly once. And it has a lifetime to ensure that it doesn’t outlive any resources it might be pointing to.

Fields

raw: *mut Opaque

_phantom: PhantomData<(&'a (), Num)>
