Trait Implementations

impl Clone for IStreamAsync

fn clone(&self) -> IStreamAsync

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IStreamAsync

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

Formats the value using the given formatter.

impl From<&IStreamAsync> for ISequentialStream

fn from(value: &IStreamAsync) -> Self

Converts to this type from the input type.

impl From<&IStreamAsync> for IStream

fn from(value: &IStreamAsync) -> Self

Converts to this type from the input type.

impl From<&IStreamAsync> for IUnknown

fn from(value: &IStreamAsync) -> Self

Converts to this type from the input type.

impl From<IStreamAsync> for ISequentialStream

fn from(value: IStreamAsync) -> Self

Converts to this type from the input type.

impl From<IStreamAsync> for IStream

fn from(value: IStreamAsync) -> Self

Converts to this type from the input type.

impl From<IStreamAsync> for IUnknown

fn from(value: IStreamAsync) -> Self

Converts to this type from the input type.

impl Interface for IStreamAsync

const IID: Guid

type Vtable = IStreamAsync_abi

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

Safety

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

where T: Interface,

Safety

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

Safety

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 PartialEq for IStreamAsync

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

Tests for self and other values to be equal, and is used by ==.

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

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