Struct CartableOptionPointer

Source 
pub struct CartableOptionPointer<C>
where
    C: CartablePointerLike,
{ /* private fields */ }
Expand description

A type with similar semantics as Option<C<T>> but with a niche.

This type cannot be publicly constructed. To use this in a Yoke, see Yoke::convert_cart_into_option_pointer.
