Struct RowHighlight 

Source 
pub struct RowHighlight {
    pub bounds: Rect,
    pub selected: bool,
    pub show_gutter: bool,
    pub gutter_char: char,
}
Expand description

Tufte-compliant row highlighting with multiple visual cues

Visual elements:

  1. Strong background color (immediate visibility)
  2. Left gutter indicator ▐ or │ (spatial cue)
  3. Optional right border (framing)
  4. Text color change (contrast)

Fields§

§bounds: Rect

The row rectangle

§selected: bool

Is this row selected?

§show_gutter: bool

Show gutter indicator

§gutter_char: char

Gutter character (default: ▐)

Implementations§

Source§

impl RowHighlight

Source

pub fn new(bounds: Rect, selected: bool) -> Self

Source

pub fn with_gutter(self, show: bool) -> Self

Source

pub fn with_gutter_char(self, ch: char) -> Self

Source

pub fn paint(&self, canvas: &mut dyn Canvas)

Paint the row highlight to a canvas

CRITICAL: Always paints to clear previous frame artifacts. Terminal buffers retain pixels - non-selected rows need explicit background.

Source

pub fn text_style(&self) -> TextStyle

Get the text style for content in this row
