Function highlight_substring 

pub fn highlight_substring(
    text: &str,
    query: &str,
    base_style: Style,
    highlight_style: Style,
) -> Line<'static>

Highlight substring matches in text (case-insensitive)

Returns a Line with matching portions styled using highlight_style. Non-matching portions use the base_style.

Example

use tui_dispatch_components::style::{highlight_substring, Style, Color, Modifier};

let base = Style::default();
let highlight = Style::default().fg(Color::Yellow).add_modifier(Modifier::BOLD);
let line = highlight_substring("Hello World", "wor", base, highlight);
// Results in: "Hello " (base) + "Wor" (highlight) + "ld" (base)

Notes

• Matching is case-insensitive
• Only works with ASCII text; non-ASCII returns the text with base style
• Empty query returns the text with base style
