Struct TextLayoutLine 

pub struct TextLayoutLine {
    pub extra_style: Vec<LineExtraStyle>,
    pub text: TextLayout,
    pub whitespaces: Option<Vec<(char, (f64, f64))>>,
    pub indent: f64,
    pub phantom_text: PhantomTextLine,
}

Fields

extra_style: Vec<LineExtraStyle>

Extra styling that should be applied to the text (x0, x1 or line display end, style)

text: TextLayout

whitespaces: Option<Vec<(char, (f64, f64))>>

indent: f64

phantom_text: PhantomTextLine

Implementations

impl TextLayoutLine

pub fn line_count(&self) -> usize

The number of line breaks in the text layout. Always at least 1. Only counts non-empty visual lines (matching old relevant_layouts behavior).

pub fn relevant_layout_count(&self) -> usize

Count of visual lines that contain non-whitespace content. Parley’s whitespace-only lines are always trailing, so we scan backwards to find the last visible line rather than filtering all lines.

pub fn layout_cols<'a>( &'a self, text_prov: impl TextLayoutProvider + 'a, line: usize, ) -> impl Iterator<Item = (usize, usize)> + 'a

Iterator over the (start, end) columns of the relevant layouts.

pub fn start_layout_cols(&self) -> impl Iterator<Item = usize>

Iterator over only the start columns of the relevant layouts. Cheaper than layout_cols — skips the end-column adjustment that involves phantom-text resolution, rope lookups and slice comparisons.

pub fn get_layout_y(&self, nth: usize) -> Option<f32>

Get the baseline y position of the given visual line index

pub fn get_layout_x(&self, nth: usize) -> Option<(f32, f32)>

Get the (start x, end x) positions of the given visual line index

Trait Implementations

impl Clone for TextLayoutLine

fn clone(&self) -> TextLayoutLine

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
