Trait FontSystem 

pub trait FontSystem {
    // Required methods
    fn load_font(&self, query: &FontQuery) -> Result<FontData, FontError>;
    fn shape_text(
        &self,
        request: &ShapeRequest<'_>,
    ) -> Result<ShapedText, FontError>;
}

Font loading and shaping boundary used by engine profiles.

Required Methods

Load font data that matches the query.

fn shape_text( &self, request: &ShapeRequest<'_>, ) -> Result<ShapedText, FontError>

Shape text into positioned glyphs.
