Trait SignalTask 

pub trait SignalTask:
    Send
    + Sync
    + 'static {
    // Required method
    fn register_task(self: Box<Self>, world: &mut World) -> SignalHandle;
}

A type-erased signal that can be managed as a free-floating “task”.

This trait enables Builder::hold_tasks to accept signals that haven’t been registered yet, deferring their registration until the entity is spawned.

Use the .task() method to convert a Signal, SignalVec, or SignalMap into a SignalTask.

Required Methods

fn register_task(self: Box<Self>, world: &mut World) -> SignalHandle

Register this signal task with the world and return its handle.
