[−][src]Trait windows::Interface

pub unsafe trait Interface: Sized + Abi {
    type Vtable;

    pub const IID: Guid;
    pub unsafe fn vtable(&self) -> &Self::Vtable { ... }

    pub unsafe fn assume_vtable<T: Interface>(&self) -> &T::Vtable { ... }

    pub fn cast<T: Interface>(&self) -> Result<T> { ... }
}

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

pub unsafe fn vtable(&self) -> &Self::Vtable[src]

Returns the vtable for the current interface.

pub unsafe fn assume_vtable<T: Interface>(&self) -> &T::Vtable[src]

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

pub fn cast<T: Interface>(&self) -> Result<T>[src]

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.
