Awesome news! Rust is easily the best programming experience I've had--the language feels incredibly well thought out, common tooling like doc generation and dependency management are included with the language, and the compiler takes full advantage of language features such that my editor's linter is able to detect most mistakes I make and the language itself guards me from doing anything obviously unsafe. I thought the rewrite-everything Rust people were annoying and that turned me off initially, but ever since getting involved with the community I've found that it's full of lots of very passionate people working on a stunning variety of interesting new projects. You really feel like you're on the ground floor of the next generation of systems programming languages, enough to where I've even considered replacing my habitual use of Python with Rust considering how easy it is to write.
Seriously, it's worth your time to explore. If you have a spare evening and want to be enchanted, highly suggest giving the Rust book a gander: https://doc.rust-lang.org/stable/book/
serious question : would you recommend Rust for CRUDdy type of web applications -- stuff where mostly you are firing off prepared statememts at a SQL db and then applying business logic to result set. This is what most J2EE apps do currently.
Since this is a side project for me, there wasn't much risk if it ended up being a bad decision. Multiple times throughout the project I got frustrated with the DX of existing http frameworks I tried and ended up building my own [2] on top of hyper. However, after launching my site and seeing how it performs in production, I could not be happier with the result! I had a bit of Rust experience before the project but learned a lot more through building this.
For you and others, I think it really depends on the situation. Building a Rust CRUD app will likely take longer than the other languages you're used to as the ecosystem is under heavy development, especially with async/await. So if you or your team are in a rush, I'll just echo that you should build with the tools you already know. If you have time and budget to experiment like I did, it might be worthwhile and I can promise it will be fun :)
