An iterator that runs all at once

Associated Types

type Item

Required Methods

fn foreach<F>(self, F) where F: FnMut(Self::Item) -> bool

Run this Iterator using the provided closure.

Return true from the closure to end the iteration.

Provided Methods

fn run<F>(self, f: F) where F: FnMut(Self::Item)

Run this Iterator using the provided closure.

This is a utility method for non-cancelling iterations.
