实现

impl GraphicsCaptureItem

pub fn DisplayName(&self) -> Result<HSTRING, Error>

pub fn Size(&self) -> Result<SizeInt32, Error>

pub fn Closed<P0>(&self, handler: P0) -> Result<i64, Error>

where P0: Param<TypedEventHandler<GraphicsCaptureItem, IInspectable>>,

pub fn RemoveClosed(&self, token: i64) -> Result<(), Error>

pub fn TryCreateFromDisplayId( displayid: DisplayId, ) -> Result<GraphicsCaptureItem, Error>

trait 实现

impl Clone for GraphicsCaptureItem

fn clone(&self) -> GraphicsCaptureItem

返回该值的一个副本。 阅读更多

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

Performs copy-assignment from source. 阅读更多

impl Debug for GraphicsCaptureItem

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

使用给定的格式化器格式化该值。 阅读更多

impl Interface for GraphicsCaptureItem

const IID: GUID = <IGraphicsCaptureItem as windows_core::Interface>::IID

与该接口关联的 GUID。

fn as_raw(&self) -> *mut c_void

返回原始的 COM 接口指针。返回的指针仍由 Interface 实现所拥有。

fn into_raw(self) -> *mut c_void

返回原始的 COM 接口指针并释放所有权。释放该 COM 接口指针是调用者的责任。

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

通过获取 raw COM 接口指针的所有权来创建一个 Interface。 阅读更多

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

创建一个在 raw COM 接口指针有效期间一直有效的 Interface。 阅读更多

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

where T: Interface,

尝试使用 QueryInterface 将当前接口转换为另一个接口。 阅读更多

fn cast_to_any<T>(&self) -> Result<&(dyn Any + 'static), Error>

where T: ComObjectInner, <T as ComObjectInner>::Outer: Any + 'static + IUnknownImpl<Impl = T>,

This casts the given COM interface to [&dyn Any]. 阅读更多

fn is_object<T>(&self) -> bool

where T: ComObjectInner, <T as ComObjectInner>::Outer: Any + 'static + IUnknownImpl<Impl = T>,

Returns true if the given COM interface refers to an implementation of T. 阅读更多

fn cast_object_ref<T>(&self) -> Result<&<T as ComObjectInner>::Outer, Error>

where T: ComObjectInner, <T as ComObjectInner>::Outer: Any + 'static + IUnknownImpl<Impl = T>,

This casts the given COM interface to [&dyn Any]. It returns a reference to the “outer” object, e.g. &MyApp_Impl, not the inner &MyApp object. 阅读更多

fn cast_object<T>(&self) -> Result<ComObject<T>, Error>

where T: ComObjectInner, <T as ComObjectInner>::Outer: Any + 'static + IUnknownImpl<Impl = T>,

This casts the given COM interface to [&dyn Any]. It returns a reference to the “outer” object, e.g. MyApp_Impl, not the inner MyApp object. 阅读更多

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

尝试创建此对象的 Weak 引用。

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

在此接口上调用 QueryInterface 阅读更多

fn to_ref(&self) -> InterfaceRef<'_, Self>

为此引用创建一个 InterfaceRef。InterfaceRef 在静态层面追踪生命周期， 无需动态引用计数调整（AddRef/Release）。

impl PartialEq for GraphicsCaptureItem

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

测试 self 与 other 的值是否相等，被 == 使用。

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

测试 !=。默认实现几乎总是足够的， 没有充分的理由不应该被重写。

impl Eq for GraphicsCaptureItem

impl Send for GraphicsCaptureItem

impl StructuralPartialEq for GraphicsCaptureItem

impl Sync for GraphicsCaptureItem
