LazySequenceType

protocol LazySequenceType : SequenceType

Returns a lazy sequence of self, chunked into arrays of adjacent equal values “`swift [1, 2, 2, 3, 1, 1, 3, 4, 2].lazy.group()

[1], [2, 2], [3], [1, 1], [3], [4], [2] ”`

  • Returns a lazy sequence of self, chunked into arrays of adjacent equal values - Parameter isEquivalent: a function that returns true if its two parameters are equal “`swift [1, 3, 5, 20, 22, 18, 6, 7].lazy.groupBy { (a,b) in abs(a - b) < 5 }

    [1, 3, 5], [20, 22, 18], [6, 7] ”`
