Split of bit shifts from #87920 into its own feature, so it can be discussed and stabilized independently.

The feature gate for the issue is #![feature(saturating_bit_shifts)].

See original discussion here: #87920 (comment)

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 it Implement saturating_shl and saturating_shr on ints #103441
• Discuss correctness of implementation
• Stabilization PR (see instructions on rustc-dev-guide)

Unresolved Questions

Can anyone confirm that this is the expected behavior for saturating bit shift operations?
