I'm not sure you can really characterise Rust as irrelevant to industry anymore (with some of the most widely used software written in Rust and FAANG companies hiring core developers), but I do agree that it has an unusually high quality standard for libraries (I'm unfamiliar with the Haskell ecosystem but I hear good things).
However, I think that while some of it is certainly cultural, a lot of it is due to the type systems in these languages being a lot more powerful which allows for more expressive APIs and more robust error handling, etc.
I was working on a decentralized website backend with a few people and while Rust has some really good libraries, damn does Diesel suck. Because of that we moved to Typescript.
Agreed that Diesel isn't great. I think it trie to be too ambitious with the type safety and shot itself in the foot. SQLx is decent, although I'm sure someone will come up with a better "Full ORM" in time.
