These features are what Marshmallow was built to provide. It is a great library, and I have used it a lot before.

But it was created before there existed Python type hints. So, to define every <abbr title="the definition of how data should be formed">schema</abbr> you need to use specific utils and classes provided by Marshmallow.

!!! check "Inspired **FastAPI** to"
    Use code to define "schemas" that provide data types and validation, automatically.

This document is an overview of how the operator works from a user perspective. For more details about the design and
architecture and a code overview, see [ARCHITECTURE.md](../architecture/environments/operator.md).

## Introduction

The operator uses the [IstioOperator API](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto), which has
three main components:

	//
	// Invariant: Defs[id] == nil || Defs[id].Pos() == id.Pos()
	Defs map[*syntax.Name]Object

	// Uses maps identifiers to the objects they denote.
	//
	// For an embedded field, Uses returns the *TypeName it denotes.
	//
	// Invariant: Uses[id].Pos() != id.Pos()
	Uses map[*syntax.Name]Object

	// Implicits maps nodes to their implicitly declared objects, if any.

 *
 * <p><b>Note:</b> by default, the returned map uses equality comparisons (the {@link Object#equals
 * equals} method) to determine equality for keys or values. However, if {@link #weakKeys} was
 * specified, the map uses identity ({@code ==}) comparisons instead for keys. Likewise, if {@link
 * #weakValues} was specified, the map uses identity comparisons for values.

	// DefaultEtcdVersion indicates the default etcd version that kubeadm uses
	DefaultEtcdVersion = "3.5.14-0"

	// Etcd defines variable used internally when referring to etcd component
	Etcd = "etcd"
	// KubeAPIServer defines variable used internally when referring to kube-apiserver component
	KubeAPIServer = "kube-apiserver"
	// KubeControllerManager defines variable used internally when referring to kube-controller-manager component
