I am trying to copy a struct of type Big to type Small without explicitly creating a new struct of type Small with the same fields.
I have tried searching for other similar problems such as this and this yet all the conversions between different struct types happen only if the structs have the same fields.
Here is an example of what I tried to do:
// Big has all the fields that Small has including some new ones.
type Big struct {
A int
B string
C float
D byte
}
type Small struct {
A int
B string
}
// This is the current solution which I hope to not use.
func ConvertFromBigToSmall(big Big) Small {
return Small{
A: big.A,
B: big.B,
}
}
I expected to be able to do something like this, yet it does not work:
big := Big{}
small := Small(big)
Is there a way of converting between Big
to Small
(and maybe even vice-versa) without using a Convert
function?
