Represents the local connection settings i.e. the settings the client is expected to use when communicating with the server. There will be a delay between calling a setter and the setting taking effect at the client. When a setter is called, the new value is added to the set of pending settings. Once the ACK is received, the new value is moved to the current settings. While waiting for the ACK, the getters will return the most lenient / generous / relaxed of the current setting and the pending setting. This class does not validate the values passed to the setters. If an invalid value is used the client will respond (almost certainly by closing the connection) as defined in the HTTP/2 specification.
