import { Iterator as Iter, IterableIterator } from '@stdlib/types/iter';

// Define a union type representing both iterable and non-iterable iterators:
type Iterator = Iter | IterableIterator;

/**
* Returns an iterator which iteratively computes `exp(x) - 1`.
*
* ## Notes
*
* -   If an environment supports `Symbol.iterator` **and** a provided iterator is iterable, the returned iterator is iterable.
*
* @param iterator - input iterator
* @returns iterator
*
* @example
* var uniform = require( '@stdlib/random-iter-uniform' );
*
* var iter = iterExpm1( uniform( -5.0, 5.0 ) );
*
* var v = iter.next().value;
* // returns <number>
*
* v = iter.next().value;
* // returns <number>
*
* v = iter.next().value;
* // returns <number>
