RFC 7250 support (Raw Public Keys) is not in the list¹ of “Current features”, but neither is it listed under “Possible future features” or even “Non-features”. GnuTLS supports this feature, so GnuTLS is what I use. What is the status of this feature in Rustls?
EDIT: I found issue #423², but the reporter is not making a compelling case, since the use case presented is for a prospective new application, yet to be written.
