I'm do not contribute to projects that enforce rustfmt formatting. I can't stand rustfmt.
BTW, I love gofmt. It doesn't actually do what everyone assumes it does. gofmt preserves single-line expressions as single-line, and preserves multi-line expressions as multi-line. It just makes existing indentation neater, preserving original style and layout of the code. Rustfmt OTOH is a bulldozer that destroys everything.
