Trait Implementations

impl Clone for IDeviceTopology

fn clone(&self) -> IDeviceTopology

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IDeviceTopology

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for IDeviceTopology

impl Interface for IDeviceTopology

type Vtable = IDeviceTopology_abi

const IID: Guid

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

Returns the vtable for the current interface.

pub unsafe fn assume_vtable<T>(&self) -> &<T as Interface>::Vtable where
    T: Interface, 

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>(&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.

impl<'a> IntoParam<'a, IUnknown> for IDeviceTopology

fn into_param(self) -> Param<'a, IUnknown>

impl<'a> IntoParam<'a, IUnknown> for &'a IDeviceTopology

fn into_param(self) -> Param<'a, IUnknown>

impl PartialEq<IDeviceTopology> for IDeviceTopology

fn eq(&self, other: &IDeviceTopology) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &IDeviceTopology) -> bool

This method tests for !=.
