5#[tuplities_derive::impl_reverse]
6/// A trait for reversing the elements of a tuple.
7///
8/// This trait provides a method to reverse the order of elements in a tuple.
9///
10/// # Examples
11///
12/// ```rust
13/// use tuplities_reverse::TupleReverse;
14///
15/// let tuple = (1, "hello", 3.14);
16/// let reversed = tuple.reverse();
17/// assert_eq!(reversed, (3.14, "hello", 1));
18/// ```
19///
20/// Part of the [`tuplities`](https://docs.rs/tuplities/latest/tuplities/) crate.
21pub trait TupleReverse {
22    /// The type of the tuple with elements in reverse order.
23    type Output;
24
25    /// Consumes the tuple and returns a new tuple with elements in reverse order.
26    fn reverse(self) -> Self::Output;
27}
