benchmark comparison workflow

[BurntSushi]

I was looking into switching from criterion to divan, and was wondering if there were any workflows for comparing benchmark results? I scanned the blog, but couldn't find anything. I'm thinking about the workflows enabled by tools I've built like cargo-benchcmp and critcmp. I would really love to not build a third tool.

The READMEs of those tools should outline the general idea of their usefulness. It's very useful to be able to compare benchmarks within the same run and also useful compare benchmarks across runs to determine if there was an improvement or a regression. Criterion somewhat attempts to do the latter for you automatically, but I find it to be incredibly clunky overall.
