I think it makes sense to update again this month if there is something we want. You need to run the update script though |

Pull Request Overview
This pull request updates Rust to yesterday's nightly, and adds an
allow()for 14 dead code warnings that surface in the tbf header module.I was motivated to submit this because upstream Rust recently switched over to LLVMs new pass manager (rust-lang/rust#88243) which seems to be able to make better decisions about inlining functions thanks to its bottom-up pass approach ensuring that callees are always maximally optimized by the time callers are being optimized.
This change reduces code size by 1232 bytes on Imix.
I realize that two rust updates in a month is more frequently than we normally update, so if we want to wait a while I understand.
