"Diff"ing iterators for caching elements to sequential collections without requiring the new
elements' iterator to be `Clone`.
- [`Diff`] (produced by the [`diff_with`] function)
describes the difference between two non-`Clone` iterators `I` and `J` after breaking ASAP from
a lock-step comparison. |

| free.rs |
Free functions that create iterator adaptors or call iterator methods.
The benefit of free functions is that they accept any [`IntoIterator`] as
argument, so the resulting code may be easier to read. |

Extra iterator adaptors, functions and macros.
To extend [`Iterator`] with methods in this crate, import
the [`Itertools`] trait:
```
use itertools::Itertools;
```
Now, new methods like [`interleave`](Itertools::interleave)
are available on all iterators:
```
use itertools::Itertools;
let it = (1..3).interleave(vec![-1, -2]);
itertools::assert_equal(it, vec![1, -1, 2, -2]);
```
Most iterator methods are also provided as functions (with the benefit
that they convert parameters using [`IntoIterator`]):
```
use itertools::interleave;
for elt in interleave(&[1, 2, 3], &[2, 3, 4]) {
/* loop body */
}
```
## Crate Features
- `use_std`
- Enabled by default.
- Disable to compile itertools using `#![no_std]`. This disables
any items that depend on collections (like `group_by`, `unique`,
`kmerge`, `join` and many more).
## Rust Version
This version of itertools requires Rust 1.32 or later. |
