MapIterator<I, S, U>.next

Method

MapIterator<I, S, U>.next() -> IteratorStep<U> where I: Iterator

Advances and transforms one source item.

Exhaustion passes through without invoking the transformation.

Effects: pure

Runtime behavior: available everywhere; synchronous

Examples

Pull one transformed item

let iterator = [1, 2].iterator().map(value => value * 10)
let first = iterator.next()
