Trait Implementations

impl Clone for IDStorageCompressionCodec

fn clone(&self) -> IDStorageCompressionCodec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComInterface for IDStorageCompressionCodec

const IID: GUID = _

A unique identifier representing this interface.

fn as_unknown(&self) -> &IUnknown

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

where T: ComInterface,

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 Debug for IDStorageCompressionCodec

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

Formats the value using the given formatter.

impl Interface for IDStorageCompressionCodec

type Vtable = IDStorageCompressionCodec_Vtbl

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.

impl PartialEq for IDStorageCompressionCodec

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