LSPObject & LSPArray are private in lib.rs #428

These should probably be public.

I'm sure it's known given the alpha state of the crate, but the LSPRequestMethods and LSPNotificationMethods enums are bit less useful without the various message structs/traits (Request, Notification, and even Response). If I create Request per the spec myself, for example, params? (in TS) is probably Option<OR2<LSPArray, LSPObject>> in Rust based on the current generated code.
