Akka.NETSubFlowOperations.Intersperse<TOut, TMat, TClosed> Method (SubFlow<TOut, TMat, TClosed>, TOut, TOut, TOut)
Intersperses stream with provided element, similar to how Join(String,String[] ) injects a separator between a collection's elements. Additionally can inject start and end marker elements to stream. In case you want to only prepend or only append an element (yet still use the intercept feature to inject a separator between elements, you may want to use the following pattern instead of the 3-argument version of intersperse (See Concat< TIn, TOut> for semantics details).

Emits when upstream emits (or before with the start element if provided)

Backpressures when downstream backpressures

Completes when upstream completes

Cancels when downstream cancels
