Struct fonts::font_template::FontTemplateDescriptor
source · pub struct FontTemplateDescriptor {
pub weight: (FontWeight, FontWeight),
pub stretch: (T, T),
pub style: (T, T),
pub unicode_range: Option<Vec<RangeInclusive<u32>>>,
}
Expand description
Describes how to select a font from a given family. This is very basic at the moment and needs to be expanded or refactored when we support more of the font styling parameters.
NB: If you change this, you will need to update style::properties::compute_font_hash()
.
Fields§
§weight: (FontWeight, FontWeight)
§stretch: (T, T)
§style: (T, T)
§unicode_range: Option<Vec<RangeInclusive<u32>>>
Implementations§
source§impl FontTemplateDescriptor
impl FontTemplateDescriptor
pub fn new(weight: FontWeight, stretch: FontStretch, style: FontStyle) -> Self
pub fn is_variation_font(&self) -> bool
sourcefn distance_from(&self, target: &FontDescriptor) -> f32
fn distance_from(&self, target: &FontDescriptor) -> f32
Returns a score indicating how far apart visually the two font descriptors are. This is used for implmenting the CSS Font Matching algorithm: https://drafts.csswg.org/css-fonts/#font-matching-algorithm.
The smaller the score, the better the fonts match. 0 indicates an exact match. This must be commutative (distance(A, B) == distance(B, A)).
fn matches(&self, descriptor_to_match: &FontDescriptor) -> bool
fn override_values_with_css_font_template_descriptors( &mut self, css_font_template_descriptors: &CSSFontFaceDescriptors, )

impl Eq for FontTemplateDescriptor
FontTemplateDescriptor contains floats, which are not Eq because of NaN. However, we know they will never be NaN, so we can manually implement Eq.
