Rc and Arc are missing new_cyclic_in

[matthewpipie]

new_cyclic was added in Rust 1.60 and allows users to create cyclic data structures without unsafe code; however, there is no equivalent new_cyclic_in. If this is an oversight, I'm happy to make a PR.

Yes, this does seem to be an oversight, feel free to make a PR.

[matthewpipie]

Great, I made a PR here: rust-lang/rust#129674.

I have a few outstanding questions in that PR. If you wouldn't mind taking a look at that, it would be much appreciated. I'm very new to the standard library and don't know some of its conventions.

[matthewpipie]

Bump! Would love some feedback on if that PR is done appropriately.

[zakarumych]

PR is still marked as "draft".

[matthewpipie]

Thank you, fixed!

[matthewpipie]

Merged!
