Enum AppLifecyclePhase 

Source
pub enum AppLifecyclePhase {
    Active,
    Inactive,
    Background,
    Foreground,
}
Expand description

The application’s lifecycle phase, as owned and reported by a mobile OS.

Inactive means visible but not receiving input (a system dialog on top), while Background means not visible at all, with process death possible at any time thereafter.
