Usage

Get Installed Applications

use app_info::get_installed_apps;

fn main() {
    let apps = get_installed_apps(64).expect("Failed to get installed apps");
    for app in apps {
        println!("App Name: {}", app.name);
        if let Some(icon) = app.icon {
            println!("Icon Size: {}x{}", icon.width, icon.height);
        }
    }
}

Find an Application by Name

use app_info::find_app_by_name;

fn main() {
    let app_name = "Calculator";
    match find_app_by_name(app_name, 64) {
        Ok(app) => println!("Found app: {}", app.name),
        Err(e) => eprintln!("Error: {}", e),
    }
}

Get File Icon

use app_info::get_file_icon;

fn main() {
    let path = "/path/to/file";
    match get_file_icon(path, 64) {
        Ok(icon) => println!("Icon Size: {}x{}", icon.width, icon.height),
        Err(e) => eprintln!("Error: {}", e),
    }
