If rust plans or tries out some changes they are not really sure about, they can start the crater thing and see if they broke anything. This is a great thing, but unfortunately it is available only for rustc, compiles literally everything, etc.
I’m in a position of a crate owner and I want to publish some changes. I believe I wouldn’t break anyone depending on me, but it would be nice if I was able to check it ahead of time.
So I was wondering if there’s some more lightweight variant of crater I could run on my own machine. It would query crates.io to list all my reverse dependencies, download these, try to patch them to link to my local version of my crate and see if they broke by that.
Does anyone know of such thing?
