## Example
```go
func main() {
decoder, err := binlog.NewBinFileDecoder("./testdata/mysql-bin.000004")
if err != nil {
panic(err)
return
}
num := 0
maxEventCount := 0
err = decoder.WalkEvent(func(event *binlog.BinEvent) (isContinue bool, err error) {
fmt.Printf("Got %s: \n\t", binlog.EventType2Str[event.Header.EventType])
fmt.Println(event.Header)
// show details if you need
// if event.Body != nil {
// pretty.Println(event.Body)
// }
//
fmt.Println(strings.Repeat("=", 100))
count ++
return maxEventCount > num || maxEventCount == 0, nil
}, nil)
if err != nil {
panic(err)
}
}
```
