Struct fonts::FontTemplate

pub struct FontTemplate {
    pub identifier: FontIdentifier,
    pub descriptor: FontTemplateDescriptor,
    pub data: Option<Arc<Vec<u8>>>,
    pub stylesheet: Option<DocumentStyleSheet>,
}

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

data: Option<Arc<Vec<u8>>>

The data to use for this FontTemplate. For web fonts, this is always filled, but for local fonts, this is loaded only lazily in layout.

stylesheet: Option<DocumentStyleSheet>

If this font is a web font, this is a reference to the stylesheet that created it. This will be used to remove this font from caches, when the stylesheet is removed.

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_for_local_font( identifier: LocalFontIdentifier, descriptor: FontTemplateDescriptor, ) -> FontTemplate

Create a new FontTemplate for a system font installed locally.

pub fn new_for_remote_web_font( url: ServoUrl, data: Arc<Vec<u8>>, css_font_template_descriptors: &CSSFontFaceDescriptors, stylesheet: Option<DocumentStyleSheet>, ) -> Result<FontTemplate, &'static str>

Create a new FontTemplate for a @font-family with a url(...) src font.

pub fn new_for_local_web_font( local_template: FontTemplateRef, css_font_template_descriptors: &CSSFontFaceDescriptors, stylesheet: DocumentStyleSheet, ) -> 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 data_if_in_memory(&self) -> Option<Arc<Vec<u8>>>

Returns a reference to the bytes in this font if they are in memory. This function never performs disk I/O.

Trait Implementations

impl Clone for FontTemplate

fn clone(&self) -> FontTemplate

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontTemplate

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl MallocSizeOf for FontTemplate

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
