Log Exporter

The log exporter is here mostly for backward compatibility (originally every variation were logged, but it can be a lot of data for a default configuration).
It will use your logger ffclient.Config.Logger to log every variation changes.

You can configure your output log with the Format field.
It uses a go template format.

Configuration example

ffclient.Config{
    // ...
   DataExporter: ffclient.DataExporter{
        Exporter: &logsexporter.Exporter{
            LogFormat: "[{{ .FormattedDate}}] user=\"{{ .UserKey}}\", flag=\"{{ .Key}}\", value=\"{{ .Value}}\"",
        },
    },
    // ...
}
