Trait Implementations

impl<'font, '_, H> GlyphCruncher<'font> for GlyphCalculatorGuard<'_, 'font, H> where
    H: BuildHasher, 

fn pixel_bounds_custom_layout<'a, S, L>(
    &mut self,
    section: S,
    custom_layout: &L
) -> Option<Rect<i32>> where
    L: GlyphPositioner + Hash,
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns the pixel bounding box for the input section using a custom layout. The box is a conservative whole number pixel rectangle that can contain the section.

fn glyphs_custom_layout<'a, S, L>(
    &'b mut self,
    section: S,
    custom_layout: &L
) -> Map<Iter<'b, (PositionedGlyph<'font>, [f32; 4], FontId)>, fn(&'b (PositionedGlyph<'font>, [f32; 4], FontId)) -> &'b PositionedGlyph<'font>> where
    L: GlyphPositioner + Hash,
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns an iterator over the PositionedGlyphs of the given section with a custom layout.
