Trait Implementations

impl Clone for IDispatch

fn clone(&self) -> IDispatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComInterface for IDispatch

const IID: GUID

A unique identifier representing this interface.

fn as_unknown(&self) -> &IUnknown

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

where T: ComInterface,

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

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

impl Debug for IDispatch

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

Formats the value using the given formatter.

impl IDispatchExt for IDispatch

fn call<S>(&self, name: S, args: Vec<VARIANT>) -> Result<VARIANT>

where S: AsRef<str>,

Call a function on this IDispatch

fn get<S>(&self, name: S) -> Result<VARIANT>

where S: AsRef<str>,

Get the value of a variable on this IDispatch

fn set<S>(&self, name: S, value: VARIANT) -> Result<VARIANT>

where S: AsRef<str>,

Set a value of a variable on this IDispatch

impl Interface for IDispatch

type Vtable = IDispatch_Vtbl

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.

impl PartialEq for IDispatch

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

impl<'a> VariantTypeExt<'a, &'a IDispatch> for VARIANT

fn variant_from(value: &'a IDispatch) -> VARIANT

Convert from a type T into a VARIANT.

fn variant_into(&'a self) -> Result<&'a IDispatch>

Convert from a VARIANT into a type, T.
