How to access a structure field through a variable?

Question

go

Hello everyone
Who knows how to refer to the structure field through a variable?
example:

type Example struct {
    field1     string
    field2     string
}

func main {
    myStruct := Example{field1: "test1", field2: "test1"}
    custom_field := "field1"
    fmt.Println(myStruct.custom_field)
}

in this form, of course, the code will not work, but I hope I outlined the main essence of my problem.
Or is it better not to do it at all?
