Struct SimpleFamily

struct SimpleFamily {
    regular: Option<FontTemplateRef>,
    bold: Option<FontTemplateRef>,
    italic: Option<FontTemplateRef>,
    bold_italic: Option<FontTemplateRef>,
}

A struct that represents the available templates in a “simple family.” A simple family is one that contains <= 4 available faces: regular, bold, italic, and bold italic. Having this simple family abstraction makes font matching much faster for families that don’t have a complex set of fonts.

This optimization is taken from: https://searchfox.org/mozilla-central/source/gfx/thebes/gfxFontEntry.cpp.

Fields

regular: Option<FontTemplateRef>

bold: Option<FontTemplateRef>

italic: Option<FontTemplateRef>

bold_italic: Option<FontTemplateRef>

Implementations

impl SimpleFamily

fn find_for_descriptor( &self, descriptor_to_match: &FontDescriptor, ) -> Option<FontTemplateRef>

Find a font in this family that matches a given descriptor.

fn default() -> SimpleFamily

Returns the “default value” for a type.

impl MallocSizeOf for SimpleFamily

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