Associated Constants

const IID: GUID

A unique identifier representing this interface.

Provided methods

source

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

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.
