RS.CLIPPY.ITER_OUT_OF_BOUNDS

Calls to `.take()` or `.skip()` that are out of bounds

What it does

Looks for iterator combinator calls such as .take(x) or .skip(x) where x is greater than the amount of items that an iterator will produce.

Why is this bad?

Taking or skipping more items than there are in an iterator either creates an iterator with all items from the original iterator or an iterator with no items at all. This is most likely not what the user intended to do.

Example

for _ in [1, 2, 3].iter().take(4) {}

Use instead:

for _ in [1, 2, 3].iter() {}
