Struct IThumbnailProvider

pub struct IThumbnailProvider(/* private fields */);

Implementations

impl IThumbnailProvider

pub unsafe fn GetThumbnail( &self, cx: u32, phbmp: *mut HBITMAP, pdwalpha: *mut WTS_ALPHATYPE, ) -> Result<()>

Trait Implementations

impl Clone for IThumbnailProvider

fn clone(&self) -> IThumbnailProvider

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IThumbnailProvider

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

Formats the value using the given formatter.

impl From<&IThumbnailProvider> for IUnknown

fn from(value: &IThumbnailProvider) -> Self

Converts to this type from the input type.

impl From<IThumbnailProvider> for IUnknown

fn from(value: IThumbnailProvider) -> Self

Converts to this type from the input type.

impl Interface for IThumbnailProvider

const IID: Guid

type Vtable = IThumbnailProvider_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 IThumbnailProvider

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