Struct TextLineRef 

pub struct TextLineRef<'a> { /* private fields */ }

A line of laid-out text in layout coordinates: byte offsets index the laid-out text and vertical positions are measured from its top.

Implementations

impl<'a> TextLineRef<'a>

pub const fn index(&self) -> usize

The line’s index in its layout.

pub const fn start(&self) -> usize

pub const fn caret_end(&self) -> usize

End of selectable/caret text on this visual line. This excludes a trailing hard line-break which has no shaped glyph of its own.

pub const fn end(&self) -> usize

pub fn baseline(&self) -> f32

pub const fn width(&self) -> f32

The unshifted advance; see TextLineRef::offset.

pub const fn offset(&self) -> f32

Horizontal alignment offset in text-area coordinates. Glyph and caret x positions already include it; consumers mapping absolute x positions add it to width instead of re-deriving the alignment.

pub fn runs(&self) -> &'a [Arc<GlyphRun>]

Glyph runs positioned relative to TextLineRef::paint_origin.

pub const fn paint_origin(&self) -> Offset

Where the line’s glyph runs are drawn: the top of its paragraph, or the layout’s origin for a whole-text layout.

pub fn glyphs(&self) -> impl ExactSizeIterator<Item = GlyphPosition> + 'a

Positioned glyphs with clusters indexing the laid-out text and y in the renderer’s negative space below the layout’s top.

pub fn clusters(&self) -> impl ExactSizeIterator<Item = TextClusterSpan> + 'a

Shaped cluster coverage in visual order; see TextClusterSpan.

pub fn selection_spans(&self, start: usize, end: usize) -> Vec<(f32, f32)>

Visual x-intervals covered by a half-open byte range of the laid-out text; see TextLine::selection_spans.

pub const fn shaped(&self) -> &'a TextLine

The shaped line in the coordinates of the text it was shaped from.
