QueryResult is returned by Execute and ExecuteStream.

As returned by Execute, len(fields) is always equal to len(row) (for each row in rows).

As returned by StreamExecute, the first QueryResult has the fields set, and subsequent QueryResult have rows set. And as Execute, len(QueryResult[0].fields) is always equal to len(row) (for each row in rows for each QueryResult in QueryResult[1:]).

type VTGateCallerID 

type VTGateCallerID struct {
	Username string `protobuf:"bytes,1,opt,name=username" json:"username,omitempty"`
}

VTGateCallerID is sent by VTGate to VTTablet to describe the caller. If possible, this information is secure. For instance, if using unique certificates that guarantee that VTGate->VTTablet traffic cannot be spoofed, then VTTablet can trust this information, and VTTablet will use it for tablet ACLs, for instance. Because of this security guarantee, this is different than the CallerID structure, which is not secure at all, because it is provided by the Vitess client.
