Struct intercom::ComItf

pub struct ComItf<T> where
    T: ?Sized,  { /* fields omitted */ }

An incoming COM interface pointer.

Intercom will implement the various [com_interface] traits for the corresponding ComItf<T> type.

This applies only to the pure interfaces. Implicit interfaces created through #[com_interface] impl MyStruct constructs are not supported for ComItf<T>.

Methods

impl<T> ComItf<T> where
    T: ?Sized, 

pub unsafe fn wrap(ptr: RawComPtr) -> ComItf<T>

Creates a ComItf<T> from a raw COM interface pointer.

Safety

The ptr must be a valid COM interface pointer for an interface of type T.

pub fn ptr(this: &Self) -> RawComPtr

Gets the raw COM pointer from the ComItf<T>.

Trait Implementations

impl<T> AsRef<ComItf<IUnknown>> for ComItf<T> where
    T: ?Sized, 

fn as_ref(&self) -> &ComItf<IUnknown>

Performs the conversion.

impl IUnknown for ComItf<IUnknown>

fn query_interface(&self, riid: REFIID) -> ComResult<RawComPtr>

Tries to get a different COM interface for the current object.

fn add_ref(&self) -> u32

Increments the reference count of the object.

fn release(&self) -> u32

Decreases the reference count of the object.

impl ISupportErrorInfo for ComItf<ISupportErrorInfo>

fn interface_supports_error_info(&self, riid: REFIID) -> HRESULT

Informs the current COM class supports IErrorInfo for a specific interface.
