# Query logging

You can set logging callbacks for every database action performed. You can use them to log interesting events with your preferred log library.

type logger struct{}
func (*logger) LogQuery(ctx context.Context, info bunny.QueryLogInfo) {
	log.Printf("Query: %s", info.Query)
}
func (*logger) LogBegin(ctx context.Context, info bunny.BeginLogInfo) context.Context {
	log.Println("Begin")
	return ctx
}
func (*logger) LogCommit(ctx context.Context, info bunny.CommitLogInfo) {
	log.Println("Commit")
}
func (*logger) LogRollback(ctx context.Context, info bunny.RollbackLogInfo) {
	log.Println("Rollback")
}

And then enable it like this at the beginning of your program:

bunny.SetLogger(&logger{})

# Transaction logging

You have the opportunity to attach your own data to the context in the LogBegin call. The returned context is passed to the inner transaction function.

This can be useful if you're attaching logging info to your context, so that all log entries made from within a transaction are annotated like so.
