Refactor to use generics to have a single Make

[sbezverk]

Hello,

 

I am starting to learn generics and I was wondering if the following code could be refactored to use genercis, in order to avoid using per type Make() method.

 

https://go.dev/play/p/gE4Z6Zj19Is

 

I have 3 identical structs, they are defined with different types and used in other types by their unique types. The function to create all 3 types can be consolidated as the actual structure of is the same.

 

I am curious it would be possible to leverage generics for this. I have made an attempt but I still need to use per type Make method.

 

Thank you and appreciate a lot your help.

There is no simple way to do this at present. This is related to
https://go.dev/issue/48522 and https://go.dev/issue/51259.

right now it only works if the structs are actually identical:

Though accessing fields is still not allowed.
