Tracking issue for `step_by` stabilization · Issue #27741 · rust-lang/rust · GitHub

Update (@SimonSapin): this is now the tracking issue for an iterator adaptor based on Iterator::nth:

pub trait Iterator {
    fn step_by(self, step: usize) -> StepBy<Self>
}

The Step trait used for making ranges iterators is now tracked at #42168.

Original issue:

The step_by method makes it possible to step through ranges with arbitrary-sized steps. There are several issues that need to be addressed before we can stabilize it:

• The design/stabiliztion of the Step trait, which is currently a bit of a mess
• The behavior on negative steps (see this thread)
• Likely the design/stabilization of Zero/One, tracked here
