How many others this object refers to.

impl<T: ?Sized> MaybeHasNiche for ObjectMarker<T>

type MnArray = NoNiche<ZeroNoNiche<<ObjectMarker<T> as Size>::Size>>

Should implement [MnArray]. Not constraint explicitly, because that breaks things.

where Self: Sized,

Restrict a value to a certain interval.
