cargo-leptos VS include-what-you-use

This is now enabled unconditionally and the Cargo.toml option is deprecated since cargo-leptos 0.2.3, it is going to be removed in 0.3

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)

Leptos got it working a couple weeks ago as well: https://github.com/leptos-rs/cargo-leptos

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.

Interesting...how does it compare to https://github.com/include-what-you-use/include-what-you-use ?

Build Insights in Visual Studio, include-what-you-use).

Looks like https://include-what-you-use.org/ might do that.

If you are worried about includes, use https://github.com/include-what-you-use/include-what-you-use and stop thinking about it.

Getting rid of that is not straightforard, though some tools can help with that

You can use the tool https://github.com/include-what-you-use/include-what-you-use to do this for for. It tracks included files and can give comment for what is used from each file. It also warns you when you include files that you don’t use

Invisible imports (e.g. traits). In Python, everything is fully namespaced (unless you from import * in which case all bets are off). It's always explicit where a name is coming from. C is the opposite: #include lets you refer to anything defined in the headers with no namespacing. That's why a common strategy (include what you use) has an associated code style: after every non-std #include you have a comment saying which of its definitions you are using. Of course, Rust is much less implicit, but I still sometimes struggle with traits. For example, you can use tokio::net::TcpStream, but you need to also use tokio::io::AsyncReadExt for the .read trait to be defined on TcpStream. This makes it hard (for me) to answer questions like "what traits are currently available in this scope?" and "why is this module being imported?"

Aside from being closed source and not available on all architectures, how does it compare to iwyu(https://include-what-you-use.org/) or clang's relatively recent include-fixer which is also accessible via clangd?

I set up include-what-you-use and I let it tell me which headers should be where. The IWYU rules would have put all needed headers including in the cpp file.
