I’m not sure I understand why editing an html template requires to recompile the rust project. I implemented a static site generator in rust for my own projects, html templates are simple liquid template files, it’s instant to recompile them. Same for stylesheets. Is the author generating the html from rust directly? If yes that sounds like a painful strategy
