Trait Implementations

impl Clone for IDirectSoundCaptureBuffer

fn clone(&self) -> IDirectSoundCaptureBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IDirectSoundCaptureBuffer

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

Formats the value using the given formatter.

impl Deref for IDirectSoundCaptureBuffer

type Target = IUnknown

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<&IDirectSoundCaptureBuffer> for &IUnknown

fn from(value: &IDirectSoundCaptureBuffer) -> Self

Converts to this type from the input type.

impl From<&IDirectSoundCaptureBuffer8> for &IDirectSoundCaptureBuffer

fn from(value: &IDirectSoundCaptureBuffer8) -> Self

Converts to this type from the input type.

impl From<IDirectSoundCaptureBuffer> for IUnknown

fn from(value: IDirectSoundCaptureBuffer) -> Self

Converts to this type from the input type.

impl From<IDirectSoundCaptureBuffer8> for IDirectSoundCaptureBuffer

fn from(value: IDirectSoundCaptureBuffer8) -> Self

Converts to this type from the input type.

impl Interface for IDirectSoundCaptureBuffer

const IID: GUID = _

The GUID associated with the interface.

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.

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

where T: Interface,

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 PartialEq for IDirectSoundCaptureBuffer

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
