Pass the “raw” Vec<VecDiff<Self::Item>> output of this SignalVec to a System, continuing propagation if the System returns Some or terminating for the frame if it returns None. Unlike most other SignalVec methods, .for_each, returns a Signal, not a SignalVec, since the output type need not be an Option<Vec<VecDiff>>. If the System logic is infallible, wrapping the result in an option is unnecessary.

where Self: Sized, Self::Item: Clone + Send + Sync + 'static,

Collect this SignalVec’s Items into a Vec, transforming it into an Signal<Item = Vec<Item>>. Read more

Place the Item output by the System between adjacent items of this SignalVec; the System takes In a Signal<Item = Option<usize>> which outputs the index of the corresponding Item or None if it has been removed. Note that the Signal<Item = Option<usize>>s are not deduped so consumers must call .dedupe if resending the same index every frame would be spurious. Read more
Source§

fn sort_by<F, M>(self, compare_system: F) -> SortBy<Self>
