Struct FontTemplate 

pub struct FontTemplate {
    pub identifier: FontIdentifier,
    pub descriptor: FontTemplateDescriptor,
    pub font_face_rule: Option<Descriptors>,
}

This describes all the information needed to create font instance handles. It contains a unique FontTemplateData structure that is platform specific.

Fields

identifier: FontIdentifier

descriptor: FontTemplateDescriptor

font_face_rule: Option<Descriptors>

If this font is a web font, this is a reference to the @font-face rule that created it.

Implementations

impl FontTemplate

Holds all of the template information for a font that is common, regardless of the number of instances of this font handle per thread.

pub fn new( identifier: FontIdentifier, descriptor: FontTemplateDescriptor, font_face_rule: Option<FontFaceRuleDescriptors>, ) -> FontTemplate

Create a new FontTemplate.

pub fn new_for_local_web_font( local_template: FontTemplateRef, css_font_template_descriptors: &CSSFontFaceDescriptors, font_face_rule: Option<FontFaceRuleDescriptors>, ) -> Result<FontTemplate, &'static str>

Create a new FontTemplate for a @font-family with a local(...) src. This takes in the template of the local font and creates a new one that reflects the properties specified by @font-family in the stylesheet.

pub fn identifier(&self) -> &FontIdentifier

pub fn compute_variations( &self, descriptor: &FontDescriptor, ) -> Vec<FontVariation>
