Trait Implementations

impl Clone for IServiceProvider

fn clone(&self) -> IServiceProvider

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IServiceProvider

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

Formats the value using the given formatter.

impl From<&'_ IFunctionInstance> for IServiceProvider

fn from(value: &IFunctionInstance) -> Self

Performs the conversion.

impl From<&'_ IServiceProvider> for IUnknown

fn from(value: &IServiceProvider) -> Self

Performs the conversion.

impl From<IFunctionInstance> for IServiceProvider

fn from(value: IFunctionInstance) -> Self

Performs the conversion.

impl From<IServiceProvider> for IUnknown

fn from(value: IServiceProvider) -> Self

Performs the conversion.

impl Interface for IServiceProvider

type Vtable = IServiceProvider_abi

const IID: GUID

A unique identifier representing this interface.

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<IServiceProvider> for IServiceProvider

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
