Trait Implementations

impl Clone for IDStorageCompressionCodec

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IDStorageCompressionCodec

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

Formats the value using the given formatter.

impl From<&IDStorageCompressionCodec> for IUnknown

fn from(value: &IDStorageCompressionCodec) -> Self

Converts to this type from the input type.

impl From<IDStorageCompressionCodec> for IUnknown

fn from(value: IDStorageCompressionCodec) -> Self

Converts to this type from the input type.

impl Interface for IDStorageCompressionCodec

const IID: GUID = _

A unique identifier representing this interface.

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.

impl PartialEq<IDStorageCompressionCodec> for IDStorageCompressionCodec

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

impl RuntimeName for IDStorageCompressionCodec

const NAME: &'static str = ""

impl Vtable 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) -> &Self

Creates an Interface that is valid so long as the raw COM interface pointer is valid.
