Required Methods

fn from_idle_args(args: &IdleArgs, old_event: &Self) -> Option<Self>

Creates an idle event.

fn idle<U, F>(&self, f: F) -> Option<U>where F: FnMut(&IdleArgs) -> U,

Calls closure if this is an idle event.

Provided Methods

fn from_dt(dt: f64, old_event: &Self) -> Option<Self>

Creates an update event with delta time.

fn idle_args(&self) -> Option<IdleArgs>

Returns idle arguments.
