Trait Implementations

impl<TResult: RuntimeType + 'static> Clone for IAsyncOperation<TResult>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<TResult: RuntimeType + 'static> ComInterface for IAsyncOperation<TResult>

const IID: GUID = _

A unique identifier representing this interface.

fn as_unknown(&self) -> &IUnknown

fn cast<T>(&self) -> Result<T, Error>where T: ComInterface,

Attempts to cast the current interface to another interface using QueryInterface.

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

Attempts to create a Weak reference to this object.

impl<TResult: RuntimeType + 'static> Debug for IAsyncOperation<TResult>

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

Formats the value using the given formatter.

impl<TResult: RuntimeType + 'static> Future for IAsyncOperation<TResult>

type Output = Result<TResult, Error>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, context: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<TResult: RuntimeType + 'static> Interface for IAsyncOperation<TResult>

type Vtable = IAsyncOperation_Vtbl<TResult>

fn as_raw(&self) -> *mut c_void

Returns the raw COM interface pointer. The resulting pointer continues to be owned by the Interface implementation.

fn into_raw(self) -> *mut c_void

Returns the raw COM interface pointer and releases ownership. It the caller’s responsibility to release the COM interface pointer.

unsafe fn from_raw(raw: *mut c_void) -> Self

Creates an Interface by taking ownership of the raw COM interface pointer.

unsafe fn from_raw_borrowed(raw: &*mut c_void) -> Option<&Self>

Creates an Interface that is valid so long as the raw COM interface pointer is valid.

impl<TResult: RuntimeType + 'static> PartialEq<IAsyncOperation<TResult>> for IAsyncOperation<TResult>

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
