case-studies VS sqlx

Luckily there is a workaround to emulate such a definition, which dtolnay discovered and explained here: https://github.com/dtolnay/case-studies/tree/b9802f6df8dc8e54970b83fb9af6df923b46abf5/unit-type-parameters.

I think they are talking about this one trick which the devs don't want you to know about. Note that while it looks like specialization, it works only in a few very limited cases and is quite fragile, so it's a hack, not a substitute for the real feature.

Also I suggest his case studies repo since you are looking at what is possible: https://github.com/dtolnay/case-studies

/u/dtolnay has a great case studies repository.

Once you have the basics down, read dtolnay's case studies. They show how to do advanced stuff with easy macros.

If you were writing your own println macro, you might be able to get away with this kind of hack: https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md

You can use "Autoref-based stable specialization" or use/mimic the impls crate.

With a subset of specialization likely riding the trains soon and a workaround available, why would you give up?

this works since values and types are in different namespaces (see: Rusts Universes or dtolnay's Case Study about "Unit struct with type parameters")

To do this with traits you would need specialization but since you are using macros you should be able to use "Autoref-based stable specialization". Here is a playground which uses the latter approach to implement the wanted macro without using any nightly features.

What exactly are you missing? I haven't really written "boring corporate backend stuff" in a few years but something like sqlx provides everything I've ever needed there.

Badges are the little rectangles you typically see at the top of a crate's README: https://github.com/launchbadge/sqlx/blob/main/README.md

SQLX has entered the chat [1].

Database : SqLite (using sqlx).

The current (well, removed) MSSQL sqlx driver also doesn't support encrypted connections (https://github.com/launchbadge/sqlx/issues/1552), so it might work locally on an unnamed instance but not over the network until they add in the newer driver (which will be closed source but for an OSS project you should be able to request a free license I think)

I'm considering making my own wrapper over lower-level database drivers. There are a lot of features in sqlx that I don't need, and the latest version seems to have removed useful data structures that SQLPage is using. It also removed support for SQL Server.

add Ed25519 to AuthPlugin enum on https://github.com/launchbadge/sqlx/blob/061fdcabd72896d9bc3abb4ea4af6712a04bc0a8/sqlx-core/src/mysql/connection/auth.rs and implement them using these crates:
