Trait Implementations§

impl Clone for IAudioEndpointOffloadStreamMeter

fn clone(&self) -> IAudioEndpointOffloadStreamMeter

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Debug for IAudioEndpointOffloadStreamMeter

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

Formats the value using the given formatter. Read more

impl Eq for IAudioEndpointOffloadStreamMeter

impl From<&IAudioEndpointOffloadStreamMeter> for IUnknown

fn from(value: &IAudioEndpointOffloadStreamMeter) -> Self

Converts to this type from the input type.

impl From<IAudioEndpointOffloadStreamMeter> for IUnknown

fn from(value: IAudioEndpointOffloadStreamMeter) -> Self

Converts to this type from the input type.

impl Interface for IAudioEndpointOffloadStreamMeter

const IID: Guid

type Vtable = IAudioEndpointOffloadStreamMeter_abi

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

Returns the vtable for the current interface.

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).

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.
