Hi Henrik, Thanks for the reply.
I do see that code in marshal.go in my gocql repo. So I should be having
this specific PR.
case TypeDate:
return unmarshalDate(info, data, value)
case TypeDate:
return marshalDate(info, value)
And the corresponding func implementations are also there.
Still I dont understand how/why it is falling into the last code block
// TODO(tux21b): add the remaining types
return nil, fmt.Errorf("can not marshal %T into %s", value, info)
Regards
Raju
