Renderable web forms library?

I'm aware of Actix and Rocket's forms support and https://github.com/kvnallsn/webforms.

webforms has the notion of rendering forms stenciled into the roadmap in the README, but it hasn't actually been implemented yet as far as I can tell.

Is there a library that has implemented render-able web forms yet? I'm accustomed to things like http://hackage.haskell.org/package/yesod-form or Django forms.

Here are some examples using yesod-form:

One of the key time-savers around Django forms and yesod-form is that they render the form with error labels when validation fails, sparing you needing to put a bunch of if conditions into your templates.

I keep revisiting snooping around for such a library because it would make migrating a project of mine to Rust a lot more palatable. I'm trying to avoid implementing a SPA if I can.

Thanks for your time.
