import static reactor.core.publisher.FluxTimeout.addNameToTimeoutDescription;

Signals a timeout (or switches to another sequence) in case a per-item generated Publisher source fires an item or completes before the next item arrives from the main source.
Type parameters:
  • <T> – the main source type
  • <U> – the value type for the timeout for the very first item
  • <V> – the value type for the timeout for the subsequent items
