33/// The error type for the frontend crate, acting as the top-level error type for the
34/// entire RisingWave project.
35// TODO(error-handling): this is migrated from the `common` crate, and there could
36// be some further refactoring to do:
37// - Some variants are never constructed.
38// - Some variants store a type-erased `BoxedError` to resolve the reverse dependency.
39//   It's not necessary anymore as the error type is now defined at the top-level.
