Custom Extensions in the Set-Cookie String

[stnwtr]

Hi,

I have some quick questions about how this crate handles the set-cookie-string and on what is defined in the RFC, or the latest draft on ietf.org.

I have seen, that the draft attribute samesite exists in this crate. But also partitioned which is only used by chromium based browsers (?) since firefox uses its "new" State Partitioning.
So the documentation on how to use partitioning (CHIPS) the right way is this one from Google and that one from Mozilla?

Since the Partitioned attribute is not mentioned in the official rfc (or draft) is is handled as one of multiple extensions which is described in 4.1.1 in the draft found with extension-av?

Is there any way in this crate to pass other (custom) extensions within a cookie?
