Ungrouped
foldable arity
Group sequential elements into fixed sized tuples by passing a "sliding window" over them.
A foldable with fewer elements than the window size will return an empty list unlike Iterable#sliding(size: Int)
.
Example:
import cats.Foldable scala> Foldable[List].sliding2((1 to 10).toList) val res0: List[(Int, Int)] = List((1,2), (2,3), (3,4), (4,5), (5,6), (6,7), (7,8), (8,9), (9,10)) scala> Foldable[List].sliding4((1 to 10).toList) val res1: List[(Int, Int, Int, Int)] = List((1,2,3,4), (2,3,4,5), (3,4,5,6), (4,5,6,7), (5,6,7,8), (6,7,8,9), (7,8,9,10)) scala> Foldable[List].sliding4((1 to 2).toList) val res2: List[(Int, Int, Int, Int)] = List()
