[−][src]Struct abi_stable::OpaqueType

#[repr(C)]

pub struct OpaqueType<T> { /* fields omitted */ }

A Zero-sized type used by VirtualWrapper<Pointer<OpaqueType<T>>>.

If this did not wrap T, we could pretend to have a T even though we don't.

Casting the pointer type to point to this type is safe, because the pointer is required to be castable to point to different types, so long as a reference to one is valid for the other.

This type intentionally does not implement any traits.
