A few days ago I saw that the Zed developers had asked for people to test their wip debugger support. I assumed this was a fair bit away, but I saw earlier today that someone wrote that it had now "shipped".

Two things I noticed:

  • In VS Code, there's a short, but noticeable lag, between pressing a step button and for it to actually perform the intended action. In Zed, it's instantaneous. Not really super important, but I always figured this was due to the protocol between the editor and the debugger, so it would always be there -- but apparently it doesn't have to be.
  • From what little I've used it, it seems that Zed displays variables properly. (In VS Code you could pretty easily get it to display garbage values in the variables section). I don't know if VS Code still has this problem these days, but it used to -- which was kind of a show-stopper for a debugger.

I use neither VS Code nor Zed for my daily work[*], so I'm mostly bringing this up because the question of Rust debuggers comes up from time to time.

[*] In fact, the reason I start VS Code is in most cases just because I need the debugger support -- but now I'll use Zed for that instead.
