## Usage

Displaying iterators.

```rust
use printable::prelude::PrintableIter;

let v = vec![1, 2, 3];
assert_eq!(format!("{}", v.iter().printable()), "[1, 2, 3]");
```

Displaying tuples.

```rust
use printable::prelude::PrintableTuple;

let v = (1, "2", 3.0);
assert_eq!(format!("{}", v.printable()), "[1, 2, 3]");
```

## Features

* __`unstable-assert-no-drop`__

  Enables compile-time assertions that the iterators used don't own any resource.

  ### Warning
  May violate backward compatibility and lead to compilation failure
  even if the major semver versions of the underlying crates aren't
  updated.

  This may happen due to the following factors:
  - The `std::mem::needs_drop` documentation does not guarantee its
  stability.
  - The fact that the iterator type, which can be declared in a third-party
  crate, started owning a resource doesn't require increasing the major
  version of this crate.
