Struct TextHighlight

pub struct TextHighlight {
    pub range: Range<usize>,
    pub color: Color,
}

Resolve the font size into a concrete logical px. Some( len ) resolves against Canvas::viewport_logical — the font space, so × dpi_scale at raster yields the right physical size — exactly like the button label; None follows the widget-scaling mode at the theme default. Shared by the draw and hit-test paths, which all carry a canvas. A run of a multiline field’s value drawn in a colour of its own, as a syntax highlighter marks keywords, strings and comments. range is in bytes of the value and should fall on character boundaries; runs are expected in order and not overlapping, and what no run covers takes the field’s colour.

Fields

range: Range<usize>

color: Color

Trait Implementations

impl Clone for Highlight

fn clone(&self) -> Highlight

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Highlight

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Highlight

fn eq(&self, other: &Highlight) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
