sourcefn data(&self) -> Arc<Vec<u8>>
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.
sourcefn descriptor(&self) -> FontTemplateDescriptor
fn descriptor(&self) -> FontTemplateDescriptor
Get the descriptor.
sourcefn identifier(&self) -> FontIdentifier
fn identifier(&self) -> FontIdentifier
Get the FontIdentifier for this template.
sourcefn matches_font_descriptor(&self, descriptor_to_match: &FontDescriptor) -> bool
fn matches_font_descriptor(&self, descriptor_to_match: &FontDescriptor) -> bool
Returns true if the given descriptor matches the one in this FontTemplate.
sourcefn descriptor_distance(&self, descriptor_to_match: &FontDescriptor) -> f32
fn descriptor_distance(&self, descriptor_to_match: &FontDescriptor) -> f32
Calculate the distance from this FontTemplates descriptor and return it
or None if this is not a valid FontTemplate.
sourcefn char_in_unicode_range(&self, character: char) -> bool
fn char_in_unicode_range(&self, character: char) -> bool
Whether or not this character is in the unicode ranges specified in
this temlates @font-face definition, if any.
