impl Interface for IWiaDevMgr

§

const IID: GUID = _

The GUID associated with the interface.
§

fn as_raw(&self) -> *mut c_void

Returns the raw COM interface pointer. The resulting pointer continues to be owned by the Interface implementation.
§

fn into_raw(self) -> *mut c_void

Returns the raw COM interface pointer and releases ownership. It the caller’s responsibility to release the COM interface pointer.
§

unsafe fn from_raw(raw: *mut c_void) -> Self

Creates an Interface by taking ownership of the raw COM interface pointer. Read more
§

unsafe fn from_raw_borrowed(raw: &*mut c_void) -> Option<&Self>

Creates an Interface that is valid so long as the raw COM interface pointer is valid. Read more
§

fn cast<T>(&self) -> Result<T, Error>
where T: Interface,

Attempts to cast the current interface to another interface using QueryInterface. Read more
§

fn cast_to_any<T>(&self) -> Result<&(dyn Any + 'static), Error>
where T: ComObjectInner, <T as ComObjectInner>::Outer: Any + 'static + IUnknownImpl<Impl = T>,
