FusedIterator is a marker trait that promises that the implementing iterator continues to return `None` from `.next()` once it has returned `None` once (and/or `.next_back()`, if implemented). The effects of FusedIterator are already widely available through `.fuse()`, but with stable `FusedIterator`, stable Rust users can implement this trait for their iterators when appropriate.
Also fix a spelling mistake.
This Python script converts documentation comments from the `#[doc = "..."]` attribute to the `///` syntax. It was added six years ago, presumably to help with the transition when `///` was implemented and hasn't really been touched since. I don't think there's much value in keeping it around at this point.

Same error. Some PR is significantly slowing down the jobs. The timeout happens at stage0-std, meaning changes to rustc only are completely irrelevant.
(⭕️ = irrelevant, I'm going to remove #48647 because a related bug, #48192, was introduced by sccache. |

Optimize str::repeat Improves the performance of `str::repeat` by bulk copying.
