Pack elements

Returns stream elements as Pack

Convert to Array

Returns stream elements as Array

 val a : Array[Int] =  (1 <> 10).stream.toArray

Convert to Buffer

Returns stream elements as Buffer

Convert to Idx

Convert to Lookup

Note. This operation is only available for streams holding tuples, like (KEY,VALUE)

Converts a stream of tuples to Lookup

val intLookup : Lookup[Int,Char] = ('A' <> 'F').stream.zipKey(_.toInt).toLookup

intLookup.pairStream.tp   // Prints Stream((69,E), (70,F), (65,A), (66,B), (67,C), (68,D))

val charLookup : Lookup[Char,Int] = ('A' <> 'F').stream.zipValue(_.toInt).toLookup

charLookup.pairStream.tp   // Prints Stream((E,69), (F,70), (A,65), (B,66), (C,67), (D,68))

Convert to Lookup

Converts stream to a Lookup collection, where key is created with provided function

val intLookup : Lookup[Int,Char] = ('A' <> 'F').stream.toLookupBy(_.toInt)

intLookup.pairStream.tp   // Prints Stream((69,E), (70,F), (65,A), (66,B), (67,C), (68,D))

Convert to unique collection

Returns stream elements as Set
