Struct IServiceProvider 

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

Implementations

impl IServiceProvider

pub unsafe fn QueryService( &self, guidservice: *const Guid, riid: *const Guid, ppvobject: *mut *mut c_void, ) -> ErrorCode

Trait Implementations

impl Clone for IServiceProvider

fn clone(&self) -> IServiceProvider

Returns a duplicate 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<&IServiceProvider> for IUnknown

fn from(value: &IServiceProvider) -> Self

Converts to this type from the input type.

impl From<IServiceProvider> for IUnknown

fn from(value: IServiceProvider) -> Self

Converts to this type from the input type.

impl Interface for IServiceProvider

const IID: Guid

type Vtable = IServiceProvider_abi

unsafe fn vtable(&self) -> &Self::Vtable

Returns the vtable for the current interface.

unsafe fn assume_vtable<T>(&self) -> &<T as Interface>::Vtable

where T: Interface,

Returns the vtable for an assumed interface. The name comes from Box’s assume_init method as it assumes the vtable is implemented by the current interface’s vtable (e.g. a parent 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.

impl<'a> IntoParam<'a, IUnknown> for &'a IServiceProvider

fn into_param(self) -> Param<'a, IUnknown>

impl<'a> IntoParam<'a, IUnknown> for IServiceProvider

fn into_param(self) -> Param<'a, IUnknown>

impl PartialEq for IServiceProvider

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