pub fn validate_client_setup(msg: &ClientSetup) -> Result<(), SetupError>Expand description
Validate a CLIENT_SETUP message.
Section 7.2.2.2 puts no role restriction on MAX_SUBSCRIBE_ID: it “communicates an initial value for the Maximum Subscribe ID to the receiving subscriber”, which is something either endpoint may do, and a client that grants the server a subscribe budget during setup is doing exactly that. PATH is the restricted parameter, and it belongs to the client, so a CLIENT_SETUP is where it is legal.
§Errors
SetupError::EmptyVersionList if no version is offered.
