# next()

Produces the next element in the drop-first sequence.

```
mutating func next() async rethrows -> Base.Element?
```

## Discussion

Until reaching the number of elements to drop, this iterator calls
`next()` on its base iterator and discards the result. If the base
iterator returns `nil`, indicating the end of the sequence, this
iterator returns `nil`. After reaching the number of elements to
drop, this iterator passes along the result of calling `next()` on
the base iterator.
