Is there a convinient way to get cookies from ReqHeader?

[ModProg]

I know that I can parse them manually, but my question is, is there a convenience method like HttpRequest::cookie(&str), to get them from RequestHead in a guard?
And if not, would that be something to consider adding, maybe in a trait both implement?

[ModProg]

Well NVM I cannot use it the way I wanted anyway, because I cannot query the database in a guard.

It's not convenient to get cookies in a guard with current methods. Tracking feature addition here: #2575
