Event data from Smart Contract parsing issue with go-ethereum - go

Question

I am unable to get the full data emitted from SC event by using types.Log channel. Is there any way so that I can have all the data from an event emitted?
The event I'm trying to parse:
PairCreated(address indexed,address indexed,address,uint)
My code:
for {
select {
case err := <-sub.Err():
log.Fatal(err)
case vLog := <-logs:
fmt.Printf("Log Block Number: %d\n", vLog.BlockNumber)
fmt.Printf("Log Index: %d\n", vLog.Index)
event := make(map[string]interface{})
err := contractAbi.UnpackIntoMap(event, "PairCreated", vLog.Data)
if err != nil {
log.Fatal(err)
}
fmt.Println(event)
}
}
I could only parse the last two arguments of the event.

I understood what was wrong here.
If an argument is declared as indexed that argument goes to Topics instead of Data. And there can be at most 3 topics. So, I tried to unpack the topics but failed. And succeeded with the following way:
token1 := common.HexToAddress(vLog.Topics[1].Hex())
token2 := common.HexToAddress(vLog.Topics[2].Hex())
And pair was in Data
So, the final code is:
for {
select {
case err := <-sub.Err():
log.Fatal(err)
case vLog := <-logs:
fmt.Printf("Log Block Number: %d\n", vLog.BlockNumber)
fmt.Printf("Log Index: %d\n", vLog.Index)
event := make(map[string]interface{})
err := contractAbi.UnpackIntoMap(event, "PairCreated", vLog.Data)
if err != nil {
log.Fatal(err)
}
fmt.Println(event)
token1 := common.HexToAddress(vLog.Topics[1].Hex())
token2 := common.HexToAddress(vLog.Topics[2].Hex())
}
}
