fn check_role(parameters: &[KeyValuePair]) -> Result<(), SetupError>Expand description
Hold a setup message to the ROLE rule.
Section 6.2.2.1: “Both endpoints MUST send a ROLE parameter with one of the
three values specified above. Both endpoints MUST close the session if the
ROLE parameter is missing or is not one of the three above-specified
values.” The three values are the ones Role names, and this is the only
draft that states the rule at all - draft-08 removed the parameter, so no
later draft has a ROLE to check.
