Expand description

Provides low-level access to a COM interface.

This trait is automatically used by the generated bindings and should not be used directly.

Provided methods

Safety

Returns the vtable for the current interface.

Safety

Returns the vtable for an assumed interface. The name comes from Box::assume_init() as it assumes the vtable is implemented by the current interface’s vtable (e.g. a parent interface).

Safety

Attempts to cast the current interface to another interface using QueryInterface. The name cast is preferred to query because there is a WinRT method named query but not one named cast.

Attempts to create a Weak reference to this object.
