mapWhile<U> method

Iter<U> mapWhile<U>(
  1. U? f(
    1. T
    )
)

Creates an iterator that both yields elements based on a predicate and maps. It will call this closure on each element of the iterator, and yield elements while it returns Some(_).

Implementation

Iter<U> mapWhile<U>(U? Function(T) f) {
  return Iter.fromIterable(_mapWhileHelper(f));
}
