Implementations

impl ShapeLine

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

Shape a line into a set of spans, using a scratch buffer. If unicode_bidi::BidiInfo detects multiple paragraphs, they will be joined.

Panics

Will panic if line contains multiple paragraphs that do not have matching direction

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

See Self::new.

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

Panics

Will panic if line contains multiple paragraphs that do not have matching direction

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

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