Discovered this through the unstable
checked_sub_signed. Looks like the impl (#126046) was merged last year. What's needed to stabilize this?rustbot commentedon Jun 3, 2025

@Amanieu @rust-lang/libs Can we start FCP on this? The ACP (rust-lang/libs-team#386) and implementation (#126046) passed last year.

I'm not a huge fan of
overflowing_*methods but I think it's fine in this case since it is consistent with the existing ones. The other methods seem fine to me.@rfcbot merge

Team member @Amanieu has proposed to merge this. The next step is review by the rest of the tagged team members:
No concerns currently listed.
Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!
See this document for info about what commands tagged team members can give me.
