Trait Implementations

impl Clone for IAudioSessionEvents[src]

fn clone(&self) -> IAudioSessionEvents[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

Performs copy-assignment from source. Read more

impl Debug for IAudioSessionEvents[src]

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

Formats the value using the given formatter. Read more

impl Interface for IAudioSessionEvents[src]

type Vtable = IAudioSessionEvents_abi

const IID: Guid[src]

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). Read more

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. Read more

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

Attempts to create a Weak reference to this object.

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

impl PartialEq<IAudioSessionEvents> for IAudioSessionEvents[src]

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

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

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

This method tests for !=.
