import ( "fmt" "gopkg.in/mgo.v2/bson" ) func main() { hex := "507f1f77bcf86cd799439011" id := bson.ObjectIdHex(hex) fmt.Println(id) }This code takes a hexadecimal string representing a MongoDB ObjectId and converts it to an ObjectId using the `bson.ObjectIdHex()` function. The resulting ObjectId is then printed to the console. In summary, the gopkg.in.mgo.v2.bson ObjectId Hex package is used for marshaling and unmarshaling MongoDB ObjectIds to and from hexadecimal strings.
