Struct HighlightRange 

pub struct HighlightRange {
    pub start_line: usize,
    pub line_count: usize,
}

A highlighted line range within a scrollable region.

Used with ScrollState::set_highlights to mark search results, error lines, or any per-line emphasis. The scrollable_with_gutter widget reads the active highlights and renders a background band on matching lines.

Fields

start_line: usize

First line (0-based, relative to content top).

line_count: usize

Number of lines in the range (1 = single line).

Implementations

impl HighlightRange

pub fn line(line: usize) -> Self

Create a single-line highlight at line.

Field-name pairing: start_line + line_count → constructor named line. Use Self::span for multi-line ranges.

pub fn span(start_line: usize, line_count: usize) -> Self

Create a multi-line highlight starting at start_line covering line_count rows.

pub fn contains(&self, line: usize) -> bool

Check whether the given absolute line index falls within this range.

Trait Implementations

impl Clone for HighlightRange

fn clone(&self) -> HighlightRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HighlightRange

impl Debug for HighlightRange

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

Formats the value using the given formatter.

impl Eq for HighlightRange

impl PartialEq for HighlightRange

fn eq(&self, other: &HighlightRange) -> 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.
