I did the same with my blog which is written in rust https://github.com/prabirshrestha/rblog. While it could be static I wanted it to be server. But I don't think rust is the reason for it. Not depending on external resources such as fonts and javascript for critical path along with compression is the most critical. Since it is a blog focus on text instead of fancy images and only include when absolutely necessary. Testing the site in Fast 3G or Slow 3G is the best way to find the places where you can optimize your site.
Looking forward to the WASM integration. Being able to use plain filesystem such as nextcloud and able to run it there would be great. I have been trying to get juypterlite wasm in my next cloud alternative that I have been working so would love to try this.
Was surprised that rust didn’t have vfs libraries. Created my own async-vfs crate but now using opendal for a Nextcloud alternative that I have been working in rust.
My go to these days has been https://github.com/hrsh7th/vim-vsnip. It is compatible with LSP and VSCode snippet format. Since it is in pure VimScript you don’t need to battle configuring python just to get the plug-in to work.
