Diesel is an incredibly beautiful ORM, but the size of the DSL means that despite Rust's state-of-the-art IDE integration I'm back to editing code, waiting for it to compile (as soon as I stop typing) and changing random shit if there are red squiggles.

The error messages are totally unreadable, all in-code references point me to meaninglessly generic abstractions, and a good portion of the impls are generated by macros so I can't even look at an actual final definition.

The confidence that if it compiles it'll run is stil there, but nothing else.
