It is hoedown currently, but we would like to move towards some kind of CommonMark. It's not officially specified.
But that doesn't seem to be right since
rustdoc supports tables which aren't available in CommonMark. Does
rustdoc support CommonMark with some set of extensions? If so, exactly what extensions does
I'd like to submit a PR to fix the documentation so it clarifies which extensions to CommonMark
Yes, it is commonmark plus some extensions that are common with GFM.
I am not sure exactly what the list is, as I don't maintain rustdoc personally. Filing an issue might be the way to go if you want to get some help there.
