    xs: I,
) -> ExhaustivePairs1Input<I> 
where
    I::Item: Clone,

This documentation applies not only to exhaustive_pairs_from_single, but also to exhaustive_triples_from_single, exhaustive_quadruples_from_single, and so on. See exhaustive_tuples_1_input for more information.

Generates all $n$-tuples with elements from a single iterator.

If xs is finite, the output length is $k^n$, where $k$ is xs.count() and $n$ is the width of the tuples. If xs is infinite, the output is also infinite.

If xs is empty, the output is also empty.
