我正在尝试根据正在编译应用程序的设备来更改应用程序的图标（我正在使用 crate 加载image） 。不幸的是，当尝试运行代码时：

    let (icon_rgba, icon_width, icon_height) = {
        let icon = if cfg!(target_os = "macos") {
            include_bytes!("../assets/icon-macos.png")
        } else {
            include_bytes!("../assets/icon.png")
        };
        let image = image::load_from_memory(icon)
            .expect("Failed to open icon path")
            .into_rgba8();
        let (width, height) = image.dimensions();
        let rgba = image.into_raw();
        (rgba, width, height)
    };

我收到以下错误：

error[E0308]: `if` and `else` have incompatible types
