1//! A trait for removing elements at specific indices from tuples.
2//!
3//! This crate provides the `TupleRemove<Idx>` trait, which allows removing an element
4//! at a compile-time known index from a tuple, returning the element and the
5//! remaining tuple.

11/// This trait allows removing an element at compile-time known index `Idx`
12/// from a tuple, returning the element and the remaining tuple.

14/// # Examples
15///
16/// ```
17/// use tuplities_remove::TupleRemove;
18/// use typenum::U1;
19///
20/// let tuple = (1, "hello", 3.14);
21/// let (removed, remainder) = TupleRemove::<U1>::remove(tuple);
22/// assert_eq!(removed, "hello");
23/// assert_eq!(remainder, (1, 3.14));
24/// ```
