feat: allow to pick Arc vs Rc via GATs?

[dzmitry-lahoda]

Given Rust GATs are stable for a while, can use these go make imbl Arc/Rc generic?

For example https://www.youtube.com/watch?v=JwG-Wa7dOBU

It will allow same code run in multi and single thread scenarios

Probably! We had some discussion here already. Mostly, it's just waiting for someone to try to do it 😄

[dzmitry-lahoda]

If one would try to do that, what is most promising code lines to plug changes to get code compile asap?

I mean what data structure and what line I can modify towards, can compilation broken, and than fixing it, and get test passed?

Maybe use the archery crate? That is what rpds uses.

[jneem]

Sure, that might make the implementation easier. (Although archery predates GATs, right? Maybe it can be done better without archery now? I haven't explored the possibilities...)
