This is a tracking issue for changing the formatting of where clauses to be formatted on a single line in some additional contexts, provided they meet certain constraints (short, single bound, and no = on aliases)

About tracking issues

Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions. A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Steps

• Implement in nightly Rust 2024.
• Add documentation to the edition guide.
  • 2024: Add chapter on single-line where clauses edition-guide#340
  • Revert "2024: Add chapter on single-line where clauses" edition-guide#344
• Add formatting for new syntax to the style guide.
  • See the nightly style procedure.
  • style-guide: Format single associated type where clauses on the same line #119515
• Ensure ready for Rust 2024 stabilization.
