use sqlx;
FEAT Can initialize the database and fail to retrieve a page. In the great tradition of TPP, this is a win. We've gone through the test driven development, and there is so much *learning* here: - tokio::test NEEDS the threaded_schedular feature to report errors correctly - thiserror can't do enum variants the way I expected - Different error types for different returns is not kosher - Serde's configuration NEEDS a type, such as JSON, to work, - Rust has include_str!(), to embed text in a Rust program from an external source - SQLX is still a pain, but it's managable.

derive_builder pattern is applied successfully. This is mostly an exercise to understand the derive_builder pattern. It required a few tips to get it working, but in the end, it's actually what I want. I also learned a lot about how the Executor pattern, the Results<> object, error mapping, and futures interact in this code. This is going to be incredibly useful long-term, as long as I still keep this project "live" in my head.
