fn AddListener( &self, listener: Ref<'_, IDWriteFontDownloadListener>, ) -> Result<u32>

fn RemoveListener(&self, token: u32) -> Result<()>

fn IsEmpty(&self) -> BOOL

fn BeginDownload(&self, context: Ref<'_, IUnknown>) -> Result<()>

This trait is not dyn compatible.

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