Hi! Rust Sitter creator here, happy to answer any questions about the project and where it's going!

Great project!

I'm curious about the set of available parser annotations. I went through the list but I didn't see anything which allows for optional elements. One example would be dangling commas. Did I miss it or are there plans to support such constructs?

[shadaj]

We support optional elements by wrapping them in `Option<T>` (other annotations are applied to the contents of the option)! So you can define

  struct ... {
    ...
    #[rust_sitter::leaf(text = ",")
    _dangling_comma: Option<()>
  }

Perfect, thanks!
