How to add erro recovery/fault tolerant with LSP ?

[phodal]

Hello, we try to add VSCode plugin for our DSL fklang. In here we decide to create a LSP from our cli.

So, we need to know do we have any suggestions/practises to works with that ? or other suggestions?

for example, we try to translate from error positives, but it seems not a good idea.

pub fn parse(code: &str) -> ParseResult<Vec<FklDeclaration>> {
  match inner_parse(code) {
    Err(e) => {
      // match &e.variant {
      //   ErrorVariant::CustomError { message } => {
      //     println!("Custom error: {}", message);
      //   }
      //   ErrorVariant::ParsingError { positives, negatives } => {
      //     positives.iter().for_each(|p| println!("Positive: {:?}", p));
      //     negatives.iter().for_each(|p| println!("Negative: {:?}", p));
      //     println!("Parsing error: positives: {:?}, negatives: {:?}", positives, negatives);
      //   }
      // };

      return Err(ParseError::msg(e.to_string()));
    }
    Ok(pairs) => {
      Ok(consume_declarations(pairs))
    }
  }
}
