2169: MBE: Mapping spans for goto definition r=matklad a=edwin0cheng Currently, go to definition gives the wrong span in MBE. This PR implement a mapping mechanism to fix it and it could be used for future MBE hygiene implementation. The basic idea of the mapping is: 1. When expanding the macro, generated 2 `TokenMap` which maps the macro args and macro defs between tokens and input text-ranges. 2. Before converting generated `TokenTree` to `SyntaxNode`, generated a `ExpandedRangeMap` which is a mapping between token and output text-ranges. 3. Using these 3 mappings to construct an `ExpansionInfo` which can map between input text ranges and output text ranges. Co-authored-by: Edwin Cheng <edwin0cheng@gmail.com> |
