Range sliders

[MrAliSalehi]

Im not sure if the title is the correct name for this, and im not sure if it already exist, I looked for it but I didnt find anything.
take a look at this code:

ui.horizontal(|ui| {
    ui.label("from:");
    let from = self.from;
    ui.add(egui::Slider::new(&mut self.from, 0..=from + 30)
        .smart_aim(false)
        .drag_value_speed(1.0)
        .step_by(1.0));

    ui.label("to:");
    ui.add(egui::Slider::new(&mut self.to, self.from + 30..=350)
        .smart_aim(false)
        .drag_value_speed(1.0)
        .step_by(1.0));
});

I'm trying to get a Range from user, so basically a From Number & To Number , the provided code "kinda" works but its not really beautiful, its a bit smelly and poor😂.
