+Can I convert a []T to an []interface{}?

+ +

+Not directly because they do not have the same representation in memory. +It is necessary to copy the elements individually to the destination +slice. This example converts a slice of int to a slice of +interface{}: +

+ +
+t := []int{1, 2, 3, 4}
+s := make([]interface{}, len(t))
+for i, v := range t {
+	s[i] = v
+}
