extension def combineWith[A](left: Signal[A])[B](right: Signal[B])(using leftShape: Signal.TupleShape[A], rightShape: Signal.TupleShape[B]): Signal[Tuple.Concat[leftShape.Out, rightShape.Out]]

Combines two signals by shallowly concatenating statically tuple-valued operands.

The render engine validates scope compatibility and samples the left input first.

extension def combineWithFn[A](left: Signal[A])[B, Result](right: Signal[B])(f: (A, B) => Result): Signal[Result]

Combines two signals and derives a value when sampled, without flattening either input. The render engine validates scope compatibility and samples the left input first.

Methods2

def combine[Signals <: NonEmptyTuple](signals: Signals)(using signalsOnly: <:<[Tuple.Union[Signals], Signal[?]]): Signal[Tuple.InverseMap[Signals, ([A] =>> Signal[A])]]

Combines a non-empty tuple of signals, preserving one result element per signal.

The render engine validates scope compatibility and samples inputs from left to right.

Defined by scalive.Signal.combine. View source (scalive/api/src/scalive/Signal.scala:37-51)

def combineWithFn[Signals <: NonEmptyTuple, Result](signals: Signals)(using signalsOnly: <:<[Tuple.Union[Signals], Signal[?]])(f: Tuple.InverseMap[Signals, ([A] =>> Signal[A])] => Result): Signal[Result]

Combines signals and derives a value when the render engine samples the result. Scope validation and left-to-right input sampling are the same as combine.

Pass .tupled for a pre-existing FunctionN. Tuples containing Nothing also require a typed function's .tupled form because Scala cannot untuple an untyped lambda over them.
