Struct ComRc 

pub struct ComRc<T: ComInterface + ?Sized> { /* private fields */ }

Reference counted handle to the ComBox data.

Provides a safe way to handle the unsafe ComBox values.

Implementations

impl<T: ComInterface + ?Sized> ComRc<T>

pub unsafe fn attach(itf: ComItf<T>) -> ComRc<T>

Attaches a floating ComItf reference and brings it under managed reference counting.

Does not increment the reference count.

Safety

Given this does not increment the reference count, it must be used only if the ComItf is one that would leave the reference dangling. If something already owns the ComItf and will do release on it, the drop of the returned ComRc will result in a double-release.

pub fn detach(rc: ComRc<T>) -> ComItf<T>

Attaches a floating ComItf reference and brings it under managed reference counting.

Does not increment the reference count.

pub unsafe fn wrap<TS: TypeSystem>(ptr: InterfacePtr<TS, T>) -> ComRc<T>

Creates a ComItf<T> from a raw type system COM interface pointer..

Does not increment the reference count.

Safety

The ptr must be owned by us. wrap will not call add_ref on the ptr.
