Trait erasable::ErasablePtr

pub unsafe trait ErasablePtr {
    fn erase(this: Self) -> ErasedPtr;
    unsafe fn unerase(this: ErasedPtr) -> Self;
}

A (smart) pointer type that can be type-erased (making a thin pointer).

When implementing this trait, you should implement it for all Erasable pointee types.

Required methods

fn erase(this: Self) -> ErasedPtr

Turn this erasable pointer into an erased pointer.

To retrieve the original pointer, use unerase.

unsafe fn unerase(this: ErasedPtr) -> Self

Unerase this erased pointer.

Safety

The erased pointer must have been created by erase.
