Struct Iterable 

pub struct Iterable<I>(pub I);

Converts a Rust iterator into a JavaScript iterable object.

The resulting object implements the JavaScript iterable protocol with a [Symbol.iterator] method that returns an iterator following the iterator protocol.

Note: The iterator can only be consumed once. Subsequent iterations will yield no values.

Example

// Create an iterable from a Vec
let iter = Iterable::from(vec![1, 2, 3]);
ctx.globals().set("myIterable", iter)?;

// Use spread operator
let result: Vec<i32> = ctx.eval("[...myIterable]")?;
assert_eq!(result, vec![1, 2, 3]);
