`is_ascii` on an empty string or slice returns true Update the description of the [`is_ascii`](https://doc.rust-lang.org/std/primitive.str.html#method.is_ascii) functions - an empty string or slice also returns `true`. This follows the pattern of [`all()`](https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.all). Clippy currently suggests to change `string.chars().all(|c| c.is_ascii())` into `string.is_ascii()`. This suggestion therefore seems fitting. I've already questioned the behavior for this multiple times. I've always had to check the internals to conclude how it works. That's why I'm opening this PR to add it directly in the documentation. |
