Struct glyph_brush::GlyphCalculatorGuard

pub struct GlyphCalculatorGuard<'brush, 'font: 'brush, H = DefaultSectionHasher> { /* private fields */ }

GlyphCalculator scoped cache lock.

Implementations

impl<H: BuildHasher> GlyphCalculatorGuard<'_, '_, H>

pub fn fonts(&self) -> &[Font<'_>]

Returns the available fonts.

The FontId corresponds to the index of the font data.

Trait Implementations

impl Debug for GlyphCalculatorGuard<'_, '_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<H> Drop for GlyphCalculatorGuard<'_, '_, H>

fn drop(&mut self)

Executes the destructor for this type.

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

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, 'b, S, L>(
    &'b mut self,
    section: S,
    custom_layout: &L
) -> PositionedGlyphIter<'b, '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.

fn pixel_bounds<'a, S>(&mut self, section: S) -> Option<Rect<i32>>where
    S: Into<Cow<'a, VariedSection<'a>>>,

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

fn glyphs<'a, 'b, S>(&'b mut self, section: S) -> PositionedGlyphIter<'b, 'font>where
    S: Into<Cow<'a, VariedSection<'a>>>,

Returns an iterator over the PositionedGlyphs of the given section.
