Struct oaidl::Ptr

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

Convenience type for holding value of *mut T Mostly just a projection of NonNull<T> functionality

Methods

puts a type into the safearray at the specified index (default impls use SafeArrayPutElement)

impl SafeArrayElement for Ptr<IUnknown>

const SFTYPE: u32

SFTYPE: u32 = VT_UNKNOWN

This is the VT value used to create the SAFEARRAY
