It is refreshingly different from other Rust templating libraries. It uses a proc-macro that compiles your HTML into Rust code. I also happen to use it in conjunction with HTMX and it works very well for me (at least in small projects).
You will still have to learn a little bit of "special" syntax though, which you are looking to avoid if I understand you correctly.
