Struct vptr::VPtr

pub struct VPtr<T, Trait: ?Sized> where
    T: HasVPtr<Trait>,  { /* fields omitted */ }

Represent a pointer to a virtual table to the trait Trait that is to be embedded in a structure T

One should not need to use this structure directly, it is going to be created by the vptr procedural macro.

Methods

impl<T, Trait: ?Sized> VPtr<T, Trait> where
    T: HasVPtr<Trait>, 

pub fn new() -> Self

Creates a new VPtr initialized to a pointer of the vtable of the Trait for the type T. Same as VPtr::default()
