# `iterator_for_each`
The tracking issue for this feature is: [#42986]
[#42986]: https://github.com/rust-lang/rust/issues/42986
------------------------
To call a closure on each element of an iterator, you can use `for_each`:
```rust
#![feature(iterator_for_each)]
fn main() {
(0..10).for_each(|i| println!("{}", i));
}
```
