Description
I am using the Go client for Prometheus, but I wonder how to parse the response data in model.Value (including Vector and Matrix). I have checked the source code, only to find the String() method to get the Vector like {pod="test-001-deployment-896b6d55b-bs586"} => 0.06435052290435223 @[1598949467.625]
{pod="test-003-deployment-665d48fb7f-dlxfb"} => 0.03620828100637146 @[1598949467.625]. So, how can I use the model data gracefully？
