in case it's not glaringly obvious from the comment, he has plenty of cpp experience and little rust experience, and that's according to his own comments

the relevant bit here is that he's porting from a language in which he has plenty of experience into another one in which he doesn't, in a large project

It's hard to articulate, but as someone who knows first hand, I just want to say that manic productivity is not the same as solid engineering.
