Tracking issue for RefCell::{replace, swap}

[alexcrichton]

Tracking issue for rust-lang/rfcs#2057

• Implement the functionality
• Add documentation
• Stabilize!

[notriddle]

Can I implement this? (I understand you'll want to give it the C-assigned label, to make sure nobody else works on it)

[alexcrichton]

Certainly!

[notriddle]

• Implemented the functionality
• What documentation is needed beyond the API docs?
• I assume that once 1.20 is released, we'll be able to talk about marking it stable.

[Havvy]

The only docs needed for this is the API docs.

I've also written PR #45819 to add a replace_with variant.

[gbip]

Is there any plan to make this stable ? I can't figure the syntax to move a value inside a RefCell to replace the old one.
Thanks !

Stabilized in #46517
