Trait IdleEvent 

pub trait IdleEvent: Sized {
    // Required methods
    fn from_idle_args(args: &IdleArgs, old_event: &Self) -> Option<Self>;
    fn idle<U, F>(&self, f: F) -> Option<U>
       where F: FnMut(&IdleArgs) -> U;

    // Provided methods
    fn from_dt(dt: f64, old_event: &Self) -> Option<Self> { ... }
    fn idle_args(&self) -> Option<IdleArgs> { ... }
}

When background tasks should be performed.

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
