Enum Lifecycle 

pub enum Lifecycle {
    Resumed,
    Inactive,
    Paused,
    Detached,
}

The application’s lifecycle state. The framework hands it to Application::on_lifecycle at every transition so the app can react: pause a timer or a camera in the background, write a save before being destroyed, and so on.

Variants

Resumed

In the foreground, visible and interactive.

Inactive

Visible but not focused — a notification shade, a system dialog, a multi-window layout. The app should not react to input but stays on screen.

Paused

In the background, not visible; on Android the render surface is lost. A good moment to release resources and suspend non-essential work.

Detached

Being destroyed — the last chance to persist state, since the process may be killed afterwards with no further notice.
