Hi Alex,
Thanks for the response. Apologies for the confusion. The Generic method
indeed uses struct fields from P1data/P2data struct(they are all same
structs). Can I still achieve this? From the below. GenericMethod should
read name field from structs.
//package p1
type P1data struct {
name string
}
//package p2
type P1data struct {
name string
}
-Thanks
