https://github.com/golang/go/issues/4373#issuecomment-671142941 go 1.16 should fix this.

NewInternalStreamIdMapper is used to assign unique ids to frames that have no initial stream id defined, such as CQL queries initiated by the proxy or ASYNC requests.

NewSystemLocalResult returns a PreparedResult if the prepareRequestInfo parameter is not nil and it returns a RowsResult if prepareRequestInfo is nil.

NewSystemPeersResult returns a PreparedResult if the prepareRequestInfo parameter is not nil and it returns a RowsResult if prepareRequestInfo is nil.

ParseCredentialsFromRequest can return nil in both credsInToken and err in case the request does not contain credentials.

AuthCredentials encapsulates a username and a password to use with plain-text authenticators.

DsePlainTextAuthenticator is a simple authenticator to perform plain-text authentications for CQL clients.

InterceptedRequestInfo on its own means that this intercepted request is a QUERY request.

FrameProcessor manages the mapping of incoming stream ids to the actual ids that are sent over to the clusters.

StreamIdMapper is used to map the incoming stream ids from the client/driver to internal ids managed by the proxy This is required because we also generate requests inside the proxy that go to the cluster through the same connection, hence they must have non-conflicting ids with user's requests.
