Trait Implementations

impl CanInto<IInspectable> for FlashControl

const QUERY: bool = false

impl CanInto<IUnknown> for FlashControl

const QUERY: bool = false

impl Clone for FlashControl

fn clone(&self) -> FlashControl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FlashControl

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

Formats the value using the given formatter.

impl From<&FlashControl> for &IInspectable

fn from(value: &FlashControl) -> Self

Converts to this type from the input type.

impl From<&FlashControl> for &IUnknown

fn from(value: &FlashControl) -> Self

Converts to this type from the input type.

impl From<FlashControl> for IInspectable

fn from(value: FlashControl) -> Self

Converts to this type from the input type.

impl From<FlashControl> for IUnknown

fn from(value: FlashControl) -> Self

Converts to this type from the input type.

impl Interface for FlashControl

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

The GUID associated with the interface.

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.

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

where T: Interface,

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

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].

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.

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.

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.

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

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

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

Call QueryInterface on this interface

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

Creates an InterfaceRef for this reference. The InterfaceRef tracks lifetimes statically, and eliminates the need for dynamic reference count adjustments (AddRef/Release).

impl PartialEq for FlashControl

fn eq(&self, other: &FlashControl) -> 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.
