This is a tracking issue for the feature leading_trailing_ones which adds trailing_ones and leading_ones to all primitive integer types. (trailing_zeros and leading_zeros already existed before.)

Lets repurpose this into a tracking issue so that you would have stuff to put into the tracking issue in the PR...

Now that here's another PR(#68165), maybe we should reopen this issue? @SimonSapin @nagisa

So we've had this for a while now, and it would be nice to stabilize. Seems pretty simple. Libs team folks?

stabilize leading_trailing_ones

This PR stabilizes the `leading_trailing_ones` feature. It's been available on nightly since the start of the year, and hasn't had any issues since. It seems unlikely we'll want to change this, so following up on @djc's suggestion in rust-lang#57969 (comment) I'd like to put forward this PR to stabilize the feature and make it part of `1.46.0`. Thanks!

Stabilized in #73032, this issue should probably be closed.
