Aleksey Kladov d8a3d6f378 internal: cleanup proc macro server error handlig ... When dealing with proc macros, there are two very different kinds of errors: * first, usual errors of "proc macro panicked on this particular input" * second, the proc macro server might day if the user, eg, kills it First kind of errors are expected and are a normal output, while the second kind are genuine IO-errors. For this reason, we use a curious nested result here: `Result<Result<T, E1>, E2>` pattern, which is 100% inspired by http://sled.rs/errors.html		2021-08-31 19:01:39 +03:00
