project-error-handling VS leptosfmt

This actually is an example of where the compiler errors could (or should have) maybe provided more help or even the potential solution, it might be worth submitting this to the error handling group.

If anyone's interested in helping to shape the future of Rust's built-in error-handling story, there's an error handling project group that's been doing great work recently, e.g. the major effort to move the Error trait into libcore ( https://github.com/rust-lang/project-error-handling/issues/3 ) and stabilizing std::backtrace. You can follow along or get involved via the #project-error-handling channel on the Rust zulip: https://rust-lang.zulipchat.com/

Getting it into alloc would enable usage in a LOT more contexts, like WASM and kernel code. Does this need a distinct tracking issue outside the ticket for moving it to core or would that just add more administrata?

without trolling https://github.com/rust-lang/project-error-handling exist and is far from having strong conclusion and anyway I will always favor enum Error anyway however I like the idea to have a opaque box in the enum for "this is a opaque error you can't deal with as a user of my api"

IIRC, the Error Handling Project Group is aware of these ideas. If this kind of thing interests you and you want to contribute, you should look into getting involved with that group.

> you should have the underlying message of the std::io::Error

This is a point of debate[1] among the error-handling working group.

Focusing on good error messages has permeated throughout the community. There's even the Error Handling Project Group if you weren't convinced how committed the language designers are to getting this right. There are a number of techniques we can use to make our errors more informative. Along the way, we will discuss the crates that can help.

The Error Handling Working Group is looking at potential breaking changes for embedded users. Maybe you could work within that group?

Leptos is a SolidJS-like framework with excellent performance. It has a great server-side story as well with server-side rendering & client-side hydration as well as what they call "server functions"; essentially define a function server-side and it can be called client-side without having to deal with http and API design. Also great tooling story with cargo-leptos, leptosfmt (as well as leptos-language-server)

Future opportunities - This one's tougher to speak to since leptos is new on the block. I think it's worth exploring leptos (or sycamore?) just to learn about fine-grained reactivity, and comparing how it works compared to a traditional react model. But to me the ecosystem around leptos is promising, with tools like cargo-letpos, leptosfmt, and more, it seems the community is stepping up to help fill some gaps.
