The planned RR recordings integration is what I'm most excited about though. Having this capability for systems languages like Rust and C++ would be transformative for complex debugging scenarios where you're often forced to restart debugging sessions from scratch after stepping past a crucial point.

View on HN

the support for system languages (the rr integration "backend") is currently closed source.

It's not ready yet, and it might be proprietary: it would be great if we can open source it, if we find a sustainable business model for that

This happens all the time and is super irksome. Being able to step backwards as well as forwards is super cool. Also, being able to do that with a loop using a slider is cool.

I need a VSCode extension for this. But alas, it's just sitting in their roadmap... Typical. Guess I'll have to roll up my sleeves and build one myself. Not like I have enough on my plate already. At least their trace files are in an open format, so it shouldn't be impossible to hook into the VS Code debugging API.

We'd love additional contributors! We also have some more detailed plans for such an extension. If you're interested in chatting about it, you can join our discord[1] (or we can expand here/in a github issue as well)
