Thanks for link doc. It is very useful. Now i think that i'm try to
use protobuf Any (as all of my struct are protobuf proto.Message.
As i understand via protobuf i can register needed Req/Rsp empty
messages via Any, and later unmarshal message to this empty structs.

Re: [go-nuts] Get struct type , save and reconstruct empty struct later

If you only need any unnamed struct type you can create one with reflect
from the field information that you can write to text somewhere.

https://godoc.org/reflect#StructOf

These unnamed struct types however do not have any methods and do not
wrap embedded named type methods.

Otherwise you probably want to register your struct types on program
initialization; for later lookup and so that they are part of the
compiled binary. The gob package does it like that for example.

Have fun!

Not sure I understood the question:

Thanks, something like this, but i need to store type in string or []byte
in db, and based on this create new empty struct.

[go-nuts] Get struct type , save and reconstruct empty struct later

[Vasiliy Tolstov]

Hi. I have reflection based question.
I need to store type of struct passed to func and later based on this
stored type reconstruct empty needed struct.
Does this possible ?
