Struct wio::com::ComPtr

#[repr(transparent)]
pub struct ComPtr<T>(_);

Methods

impl<T> ComPtr<T>

pub unsafe fn from_raw(ptr: *mut T) -> ComPtr<T> where
    T: Interface, 

Creates a ComPtr to wrap a raw pointer. It takes ownership over the pointer which means it does not call AddRef. T must be a COM interface that inherits from IUnknown.

pub fn up<U>(self) -> ComPtr<U> where
    T: Deref<Target = U>,
    U: Interface, 

Casts up the inheritance chain

pub fn into_raw(self) -> *mut T

Extracts the raw pointer. You are now responsible for releasing it yourself.

pub fn cast<U>(&self) -> Result<ComPtr<U>, i32> where
    U: Interface, 

Performs QueryInterface fun.

pub fn as_raw(&self) -> *mut T

Obtains the raw pointer without transferring ownership. Do not release this pointer because it is still owned by the ComPtr.

Trait Implementations

impl<T> Drop for ComPtr<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> PartialEq<ComPtr<T>> for ComPtr<T> where
    T: Interface, 

fn eq(&self, other: &ComPtr<T>) -> bool

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

#[must_use]

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

This method tests for !=.

impl<T> Clone for ComPtr<T> where
    T: Interface, 

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ComPtr<T>

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

Formats the value using the given formatter.

impl<T> Deref for ComPtr<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.
