(EDIT: Newlines in the code example)

Oooh, that's much closer. Not perfect, but so much better. Do you have a solution for this as well?

    →(StructType){
    →····.a = 1,
    →····.b = 2,
    →};

It's not just this scenario, but this is the worst one. It does it regardless of useTab and what's worse is that it's four spaces when both indent width and tab size are set to 8
