Fields

line_i: usize

The index of the original text line

text: &'a str

The original text line

rtl: bool

True if the original paragraph direction is RTL

glyphs: &'a [LayoutGlyph]

line_y: i32

Y offset of line

line_w: f32

width of line

Implementations

impl<'a> LayoutRun<'a>

pub fn highlight(
&self,
cursor_start: Cursor,
cursor_end: Cursor
) -> Option<(f32, f32)>

Return the pixel span Some((x_left, x_width)) of the highlighted area between cursor_start and cursor_end within this run, or None if the cursor range does not intersect this run. This may return widths of zero if cursor_start == cursor_end, if the run is empty, or if the region’s left start boundary is the same as the cursor’s end boundary or vice versa.
