> what's missing from Go that makes that impossible?
The language maintainers don't want to add it: https://github.com/golang/go/issues/19412
I haven't tried this, but I think you can get fairly close by generating the HTTP/SQL serialization code. When I get time I want to write an openapi schema amd generate the server code, write a db schema and generate the db code (I want to try https://github.com/ariga/atlas with Ent for this), then write the business logic between them and see how well it all works
I agree mostly with this, however, ownership can be strange in Rust if you’re not familiar with it. Something seemingly simple like a linked list can be challenging to implement.
I've written a few backend APIs with rust and I have to disagree. Not only have the frameworks managed to get the ergonomics similar to your popular GC lang[0][1], the natural lack of shared mutable state of HTTP handlers means you very rarely have to encounter lifetimes and a lot of the language's advanced features. What's more, now when I go back to work with other languages, I can't help but notice the significant number of unit tests I'd not have had to write in Rust. It doesn't have a Rails and Django but it's an easy pick over anything at the language level.
A note on performance, Rust's the only langauge where I haven't had the need to update my unit test harnesses to `TRUNCATE` data base data instead of creating a separate db per test on PostgresSQL.
I'll also like to mention the gem that is SQLx[1]. As someone who's never been satisfied with ORMs, type checked SQL queries that auto-populate your custom types is revolutionary. With the error-prone langauge-SQL boundary covered, I was surprised just how good it can get making use of the builtin PostgreSQL features. Almost to the point that amount of effort the community's put to building great tools like Prisma.js and feel like a fool's errand (at least so for PosgreSQL).

It is a little more complex than that these days

I am building modelbox right now - https://github.com/tensorland/modelbox I began building this in Rust while also learning the language. It became quickly very complex as I started introducing streams in async traits. I think in a few years things will get a lot better as more people use Rust for building web services, but I had to go back to Go to be more productive and ship this thing out. I loved how the compiler was forcing me to think harder about life times and such.
