what is wrong my code?

[qfihwoihfiqowhfioqhwofqof]

fn main() -> eframe::Result {
env_logger::init();
let options = eframe::NativeOptions {
viewport: eframe::ViewportBuilder::default().with_inner_size((800, 600)).build(),
..Default::default()
};
eframe::run_native(OcdGain, options, Box::new(|cc| Ok(Box::new(OcdGain::new(cc)))))
}

ui.selectable_value(&mut self.gain_crement_value, gain_crement_value::GainCrementValue::Value1_00, "Value1_00.to_string()");

These codes are the problem, how do I change them?

See below

// use eframe::egui::*;

fn main() -> eframe::Result {
    env_logger::init();
    let options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default()
            .with_inner_size([800.0, 600.0]),
        ..Default::default()
    };
    eframe::run_native(
        "OcdGain",
        options,
        Box::new(|_cc| Ok(Box::new(OcdGain::default()))),
    )
}

#[derive(Debug, Default, PartialEq)]
pub enum GainCrementValue {
    Value1_00,
    #[default]
    Value1_01,
}

#[derive(Default)]
pub struct OcdGain {
    gain_crement_value: GainCrementValue,
}

impl eframe::App for OcdGain {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.selectable_value(
                &mut self.gain_crement_value,
                GainCrementValue::Value1_00,
                "Value1_00.to_string()",
            );
            ui.selectable_value(
                &mut self.gain_crement_value,
                GainCrementValue::Value1_01,
                "Value1_01.to_string()",
            );
            ui.label(format!("Selected: {:?}", self.gain_crement_value));
        });
    }
}

I modified a few more parts of this code. Thank you
