lh123 updated this revision to Diff 389915. lh123 retitled this revision from "[clangd] Add canonical type to hover" to "[clangd] Add desugared type to hover". lh123 edited the summary of this revision. lh123 added a comment.
1. rename `CanType` to `DesugaredTy`. 2. fix some bug in compare `PrintedType`.
