Implementations

impl ShapeLine

pub fn new( font_system: &mut FontSystem, line: &str, attrs_list: &AttrsList, shaping: Shaping, tab_width: u16, direction: Direction, ) -> Self

Shape a line into a set of spans, using a scratch buffer.

When unicode_bidi::BidiInfo splits line into multiple paragraphs (on any BidiClass::B separator, e.g. LF, CR, FS, NEL, PS), the whole line is laid out in the first paragraph’s base direction.

pub fn build( &mut self, font_system: &mut FontSystem, line: &str, attrs_list: &AttrsList, shaping: Shaping, tab_width: u16, direction: Direction, )

See Self::new.

Reuses as much of the pre-existing internal allocations as possible.

pub fn layout( &self, font_size: f32, width_opt: Option<f32>, wrap: Wrap, align: Option<Align>, match_mono_width: Option<f32>, hinting: Hinting, ) -> Vec<LayoutLine>

pub fn layout_to_buffer( &self, scratch: &mut ShapeBuffer, font_size: f32, width_opt: Option<f32>, wrap: Wrap, ellipsize: Ellipsize, align: Option<Align>, layout_lines: &mut Vec<LayoutLine>, match_mono_width: Option<f32>, hinting: Hinting, )
