Required Methods

fn GetFontFamilyCount(&self) -> u32

fn GetFontFamily(&self, index: u32) -> Result<IDWriteFontFamily>

fn FindFamilyName( &self, familyname: &PCWSTR, index: *mut u32, exists: *mut BOOL, ) -> Result<()>

fn GetFontFromFontFace( &self, fontface: Ref<'_, IDWriteFontFace>, ) -> Result<IDWriteFont>

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.
