Trait Implementations

impl Clone for IWICMetadataBlockWriter

fn clone(&self) -> IWICMetadataBlockWriter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IWICMetadataBlockWriter

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

Formats the value using the given formatter.

impl From<&IWICMetadataBlockWriter> for IUnknown

fn from(value: &IWICMetadataBlockWriter) -> Self

Converts to this type from the input type.

impl From<&IWICMetadataBlockWriter> for IWICMetadataBlockReader

fn from(value: &IWICMetadataBlockWriter) -> Self

Converts to this type from the input type.

impl From<IWICMetadataBlockWriter> for IUnknown

fn from(value: IWICMetadataBlockWriter) -> Self

Converts to this type from the input type.

impl From<IWICMetadataBlockWriter> for IWICMetadataBlockReader

fn from(value: IWICMetadataBlockWriter) -> Self

Converts to this type from the input type.

impl Interface for IWICMetadataBlockWriter

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. The name cast is preferred to query because there is a WinRT method named query but not one named cast.

fn downgrade(&self) -> Result<Weak<Self>, Error>

Attempts to create a Weak reference to this object.

impl PartialEq for IWICMetadataBlockWriter

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

Tests for self and other values to be equal, and is used by ==.

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

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