Yes, but unlike most formatters where the width option is a maximum and it mostly leaves your code alone below that width, prettier will aggressively widen your code to fit if you up the print width setting.
I think rustfmt will actually also widen code you have put newlines in sometimes. But it's heuristic is somehow much better than prettier's.
