cargo-expand VS rsx

It's been superseded by https://github.com/dtolnay/cargo-expand

Try installing cargo expand, it's useful to see how macros eventually get expanded. For example, if you run cargo expand on the following code

You can use cargo expand to see what your code expands to: https://github.com/dtolnay/cargo-expand

Not too familiar with macros but does cargo-expand do what you want or did you mean something else?

Yes. You can use Tools > Expand Macro on the playground or install and run cargo-expand to see what the macro expands to. It just adds a & before the argument.

cargo expand

Along with what others are saying, there is also cargo expand which can show you what code a macro generates

Something that may help you understand code with magic proc macros is this utility. It's basically a wrapper around a Rust compiler flag that allows you to expand macros for a file.

You can use https://github.com/dtolnay/cargo-expand to examine how it works.

rsx macro is not a standard syntax, it has variants (ex. https://github.com/victorporof/rsx) . May you can define in project name that it refers to Dioxus,

For me the real cool stuff is made possible through proc macros. They take as input a stream of tokens and output a stream of tokens. For example you can use these to make embedded DSLs in rust (example JSX in rust).
