Required Methods§

fn GetMetadataFormat(&self) -> Result<GUID>

fn GetMetadataHandlerInfo(&self) -> Result<IWICMetadataHandlerInfo>

fn GetCount(&self) -> Result<u32>

fn GetValueByIndex( &self, nindex: u32, pvarschema: *mut PROPVARIANT, pvarid: *mut PROPVARIANT, pvarvalue: *mut PROPVARIANT, ) -> Result<()>

fn GetValue( &self, pvarschema: *const PROPVARIANT, pvarid: *const PROPVARIANT, pvarvalue: *mut PROPVARIANT, ) -> Result<()>

fn GetEnumerator(&self) -> Result<IWICEnumMetadataItem>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
