  11. def foldSomeLeft[B](z: B)(op: (B, A) => Option[B]): B

    Folds elements with combination function op until all elements have been processed, or op returns None.

    Folds elements with combination function op until all elements have been processed, or op returns None.

    Note: may not terminate for infinite iterators.

    def sumOp(acc: Int, e: Int): Option[Int] = if (e == 4) None else Some(acc + e)
Iterator.empty.foldSomeLeft(0)(sumOp) === 0
Iterator(1, 2, 3).foldSomeLeft(0)(sumOp) === 6
Iterator(1, 2, 3, 4, 5).foldSomeLeft(0)(sumOp) === 6

    The === operator in this pseudo code stands for 'is equivalent to'; both sides of the === give the same result.

    B

    the result type of the binary operator

    z

    the start value

    op

    the binary operator

    returns

    the result of evaluating op on the previous result of op (or z for the first time) and elements of the source iterator, stopping when all the elements have been iterated or earlier when op returns None

    Implicit
    This member is added by an implicit conversion from IteratorDecorator[A] toIterableDecorator[IteratorDecorator[A], it.type] performed by method IterableDecorator in scala.collection.decorators.This conversion will take place only if an implicit value of type IsIterable[IteratorDecorator[A]] is in scope.
    Shadowing
    This implicitly inherited member is shadowed by one or more members in this class.
    To access this member you can use a type ascription:
