Trait BackgroundActivity 

pub trait BackgroundActivity: Send + Sync {
    // Required method
    fn set_active(&self, active: bool);
}

Marks periods of important work so the platform grants background running time. Implementations are Send + Sync (the app toggles activity from its worker threads).

Required Methods

fn set_active(&self, active: bool)

true when important work starts, false when it finishes. Calls are balanced by the app but implementations must tolerate repeats.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
