§fn as_raw(&self) -> *mut c_void
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
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.
