The diff seems fine to rubber-stamp, but Rust has a no merge policy so please rebase ae2bb7b to get rid of the merge commits (preserving that it was authored by @bpangWR, of course).

[BaoshanPang]

I have been always using my personal account 'BaoshanPang' to make changes in github, but not sure why sometimes it recognize me as bpangWR which is the company account created by me.

[hanna-kruppe]

Ah, OK, then authorship is no concern, please just get rid of the merge commits in whatever way is most convenient.

[BaoshanPang]

Using a new branch is easier for me, I can't find a way to remove the "merge commits" in the current branch.
A new PR is created #65187.
