Poem

A rabbit hops through docs so neat,
Fixing errors, quick and fleet.
LessThanZero finds its true name,
rust-analyzer joins the game.
Hop, hop, hooray — small tweaks, no blame! 🐇

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The description links issue #830 and checks both items, but it does not describe the documentation-link changes.	Add a short summary explaining the corrected error references and the purpose of the rust-analyzer toolchain change.
Out of Scope Changes check	⚠️ Warning	The rust-toolchain.toml change adds rust-analyzer but is unrelated to fixing error documentation links for issue #830.	Remove the rust-analyzer change or document a direct requirement for it in issue #830 and the pull request description.
