In this case, **FastAPI** won't ever touch or care about `__init__`, we will use it directly in our code.

## Create an instance { #create-an-instance }

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

	}

	if err := target.init(); err != nil {
		return err
	}

	_, err := target.isActive()
	if err != nil {
		return err
	}
	return target.send(eventData)
}

// send - sends an event to the NSQ.
func (target *NSQTarget) send(eventData event.Event) error {
	objectName, err := url.QueryUnescape(eventData.S3.Object.Key)
	if err != nil {
		return err
	}

	// This check is verified for latest version of the object.
	DeleteAll Boolean `xml:"ExpiredObjectAllVersions"`

	set bool
}

// MarshalXML encodes delete marker boolean into an XML form.
func (b Boolean) MarshalXML(e *xml.Encoder, startElement xml.StartElement) error {
	if !b.set {
		return nil
	}
	return e.EncodeElement(b.val, startElement)
}

Those parameters are what **FastAPI** will use to "solve" the dependency.

In both cases, it will have:

* An optional `q` query parameter that is a `str`.
* A `skip` query parameter that is an `int`, with a default of `0`.
* A `limit` query parameter that is an `int`, with a default of `100`.

In both cases the data will be converted, validated, documented on the OpenAPI schema, etc.

## Use it { #use-it }
