Enum Absent 

pub enum Absent {
    Zero,
    Refuse,
}

What a request reads where the views hold nothing for it: a slot nothing is bound to, or an address or level outside its view (a structured read’s byte offset past its element is refused either way).

Variants

Zero

Zero, as Direct3D reads it (the module documentation); a buffer’s length is stated, so the executor answers its reads past the end with zero itself.

Refuse

Refused, naming the slot or the address; no buffer’s length is stated, so every read reaches the view.
