Struct windows::IUnknown[−][src]

#[repr(transparent)]
pub struct IUnknown(_);
Expand description

All COM interfaces (and thus WinRT classes and interfaces) implement IUnknown under the hood to provide reference-counted lifetime management as well as the ability to query for additional interfaces that the object may implement.

Trait Implementations

impl Clone for IUnknown[src]

fn clone(&self) -> Self[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

Performs copy-assignment from source. Read more

impl Debug for IUnknown[src]

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

Formats the value using the given formatter. Read more

impl Drop for IUnknown[src]

fn drop(&mut self)[src]

Executes the destructor for this type. Read more

impl Interface for IUnknown[src]

type Vtable = IUnknown_abi

const IID: Guid[src]

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

Returns the vtable for the current interface.

unsafe fn assume_vtable<T: Interface>(&self) -> &T::Vtable[src]

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). Read more

fn cast<T: Interface>(&self) -> Result<T>[src]

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. Read more

fn downgrade(&self) -> Result<Weak<Self>>[src]

Attempts to create a Weak reference to this object.

impl PartialEq<IUnknown> for IUnknown[src]

fn eq(&self, other: &Self) -> bool[src]

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

#[must_use]
fn ne(&self, other: &Rhs) -> bool1.0.0[src]

This method tests for !=.
