inlay-hints

lsp-rust-analyzer-inlay-hints-mode enables displaying of inlay hints

NOTE: the inlay hints interact badly with the lsp-ui sideline, because it doesn't seem to consider the overlays in its width calculation, which often leads to lines wrapping around.

Macro expansion

lsp-rust-analyzer-expand-macro expand macro call at point recursively

Use your own function for macro expansion by customizing lsp-rust-analyzer-macro-expansion-method

rustic uses a different function for macro expansion by default, because we want formatted and highlighted results.
