Required Methods

fn data(&self) -> Arc<Vec<u8>>

Returns a reference to the data in this font. This may be a hugely expensive operation (depending on the platform) which performs synchronous disk I/O and should never be done lightly.

fn descriptor(&self) -> FontTemplateDescriptor

Get the descriptor. Returns None when instantiating the data fails.

fn descriptor_matches(&self, requested_desc: &FontTemplateDescriptor) -> bool

Returns true if the given descriptor matches the one in this FontTemplate.

fn descriptor_distance( &self, requested_descriptor: &FontTemplateDescriptor ) -> f32

Calculate the distance from this FontTemplates descriptor and return it or None if this is not a valid FontTemplate.
