Struct ShapeSpan 

pub struct ShapeSpan {
    pub level: Level,
    pub words: Vec<ShapeWord>,
    pub decoration_spans: Vec<(Range<usize>, GlyphDecorationData)>,
}

A shaped span (for bidirectional processing)

Fields

level: Level

words: Vec<ShapeWord>

decoration_spans: Vec<(Range<usize>, GlyphDecorationData)>

Decoration data per user-level attr span within this shape span. Each entry maps a byte range to its decoration config and font metrics. Empty when no decorations are active.

Implementations

impl ShapeSpan

pub fn new( font_system: &mut FontSystem, line: &str, attrs_list: &AttrsList, span_range: Range<usize>, line_rtl: bool, level: Level, shaping: Shaping, ) -> Self

Shape a span into a set of words.

pub fn build( &mut self, font_system: &mut FontSystem, line: &str, attrs_list: &AttrsList, span_range: Range<usize>, line_rtl: bool, level: Level, shaping: Shaping, )

See Self::new.

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