@GeoffWozniak @ireneista I see layout as part of the form, I guess? I write source code files in much the same way as one would write chapters in a book: somewhat self-contained, and intended to make sense when read top-to-bottom linearly and with roughly one full-displayful of contex. so if rustfmt decides to blow up a function call into 20 lines out of nowhere it very much messes with that, for example
