Is there a way to get the Rust Tree using another extensinon in Vscode ?

Hi,
Working on a vscode extension where I need to parse a rust module to find a struct name. Is there a way using the rust analyzer exported API to do it ?
Thank you
Jimmy

If you just need the AST of a file, you can use our syntax crate. You can get the AST of a file with SourceFile::parse(text, edition) (although correctly determining the edition can be hard).

However, note that only parsing is not enough to correctly find a type in all cases. E.g. macros can expand to new structs. If you want to find a file in a fully analyzed project, that's also possible using our API, but it is more work and also requires analyzing the project - which can take a long time. A probably better alternative is to interact directly with the rust-analyzer VSCode extension and send it a workspace symbols command.
