Snapshots diff current with previous output and I only have to accept or reject the diff. I don't have to write the expected response myself. Snapshots can also stub out parts of the response that are not determistic.
Rewriting could also make sense if there is a chance to improve the architecture based on the experience with the existing codebase. Something that would otherwise be impossible to even consider.
where do you even base these claims? Do you know what C# and Java threads have that Rust doesn't? data races. And don't get me stated on the biggest paradigm failure that is OOP.
Agreed, RustRover is by far the best IDE for Rust atm. I also use the AI Assistant which is so toned down that it's actually useful and not full of spam.
