Trait FontSource 

pub trait FontSource {
    // Required methods
    fn family(&mut self, name: &str) -> Vec<Font>;
    fn face_for_codepoint(
        &mut self,
        codepoint: char,
        attrs: FontAttrs,
    ) -> Option<Font>;
}

FontSource locates fonts that are not already registered.

A source may consult installed fonts, downloaded assets, or another host-owned repository. FontCollection consults sources in registration order.

Required Methods

fn family(&mut self, name: &str) -> Vec<Font>

family returns every available face matching a family name.

fn face_for_codepoint( &mut self, codepoint: char, attrs: FontAttrs, ) -> Option<Font>

face_for_codepoint returns a covering face nearest to attrs.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
