Yeah, it took me a bit to wrap my head around it. It's worth it to avoid subtle, weird, and hard to diagnose bugs later on.
Rust needs some layer on top to make it more usable for the typical business apps.
I tried to build simple CRUD apps, but it's still a huge pain, because there's just so much stuff I need to do myself and so much low level overhead that I need to keep in mind.
Java is worse in many ways, but for cobbling together a mess that barely manages to do its thing, it's really great.
Isn't that the point? It doesn't let you write bad code, thus when you did manage to get something compiled it's close to C speed. Also I kinda like that it tells me ebery lil mistake, it reminds me when I forgot to delete/change something
Compared to Java, it makes me write the same data structures three or four times.
Just an example: if I want to be able to insert a struct via Diesel, I need to write the actual entity, an entity without the id for inserts and maybe some other structures for queries. Also, I need to write a schema file defining the DB plus an SQL statement for actually creating the needed tables.
Another example: explorative testing. Sometimes you need to disable chunks of code for testing purposes. Maybe that long running computation or a DB query, etc. Rust often forces you to write a bunch of "corrections" to make the code seem correct again.
I get that this is useful, but for my line of work, it's just a pain in the ass.
I can't relate to these, but Rust is lacking in some aspects that's no secret. That's why it barely has GUIs or object oriented coding. It's usable for both, but why would you. You don't have to use rust for what it's not ment to be used at.
it's trying it's best tho, lol. I wonder if in X years, it'll be like c++, a Frank Einstein of syntax to be usable for everything.
