How to listen to registry key value changes?

Question

I want to track if a value of the registry key changes. Maybe something like notify but for registry. Right now I'm getting registry value with help of windows-registry.

code:

pub fn is_light_theme() -> bool {
    let val = CURRENT_USER
        .open(r#"Software\Microsoft\Windows\CurrentVersion\Themes\Personalize"#)
        .expect("Failed to get registry key")
        .get_u32("AppsUseLightTheme")
        .expect("Failed to get registry value");
    println!("{}", val);
    val != 0
}
