[denisvasilik]

Helps with #75080.

@jyn514 We're almost finished with this issue. Thanks for mentoring. If you have other topics to work on just let me know, I will be around in Discord.

@rustbot modify labels: T-doc, A-intra-doc-links

Known issues:

• Link from core to std (Figure out a way to link to downstream crates #74481):

  [OsStr]
  [String]
  [VecDeque<T>]

Thanks so much for all your hard work! I don't have other issues in mind just at the moment, but I'm sure @Dylan-DPC or someone else will have suggestions - #73904 might be a good fit.

Broken link, needs to be re-added.

Oh I see, this is in crate::iter::traits, not in crate::iter. It's just re-exported. Yeah, reverting to the longer links is fine then.
