Unfortunately this crate has been abandoned by its author for quite some time now. The main differences are that are that chromiumoxide uses async rust by design and that all the devtools protocol types are generated.

rust-headless-chrome was very helpful for some parts and bootstrapped some parts of chromiumoxide, such as the key and mouse clicking. However I looked at chromedp and puppeteer itself for the most part.

Looks like that isn't async.
