Trait Implementations

impl Clone for IAudioSessionEvents

fn clone(&self) -> IAudioSessionEvents

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IAudioSessionEvents

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

Formats the value using the given formatter.

impl From<&'_ IAudioSessionEvents> for IUnknown

fn from(value: &IAudioSessionEvents) -> Self

Performs the conversion.

impl From<IAudioSessionEvents> for IUnknown

fn from(value: IAudioSessionEvents) -> Self

Performs the conversion.

impl Interface for IAudioSessionEvents

type Vtable = IAudioSessionEvents_abi

const IID: Guid

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::assume_init() as it assumes the vtable is implemented by the current interface’s vtable (e.g. a parent interface).

unsafe fn query(&self, iid: *const Guid, interface: *mut *mut c_void) -> HRESULT

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.

fn downgrade(&self) -> Result<Weak<Self>, Error>

Attempts to create a [Weak] reference to this object.

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

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

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

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

impl PartialEq<IAudioSessionEvents> for IAudioSessionEvents

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

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

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

This method tests for !=.
