func ValidateStructural 

func ValidateStructural(fldPath *field.Path, s *Structural) field.ErrorList

ValidateStructural checks that s is a structural schema with the invariants:

* structurality: both `ForbiddenGenerics` and `ForbiddenExtensions` only have zero values, with the two exceptions for IntOrString. * RawExtension: for every schema with `x-kubernetes-embedded-resource: true`, `x-kubernetes-preserve-unknown-fields: true` and `type: object` are set * IntOrString: for `x-kubernetes-int-or-string: true` either `type` is empty under `anyOf` and `allOf` or the schema structure is one of these:

  1. anyOf: - type: integer - type: string
  2. allOf: - anyOf: - type: integer - type: string - ... zero or more

* every specified field or array in s is also specified outside of value validation. * metadata at the root can only restrict the name and generateName, and not be specified at all in nested contexts. * additionalProperties at the root is not allowed.

Types

type Extensions 

type Extensions struct {
	// x-kubernetes-preserve-unknown-fields stops the API server
	// decoding step from pruning fields which are not specified
	// in the validation schema. This affects fields recursively,
	// but switches back to normal pruning behaviour if nested
	// properties or additionalProperties are specified in the schema.
	// False means that the pruning behaviour is inherited from the parent.
	// False does not mean to activate pruning.
	XPreserveUnknownFields bool

	// x-kubernetes-embedded-resource defines that the value is an
	// embedded Kubernetes runtime.Object, with TypeMeta and
	// ObjectMeta. The type must be object. It is allowed to further
	// restrict the embedded object. Both ObjectMeta and TypeMeta
	// are validated automatically. x-kubernetes-preserve-unknown-fields
	// must be true.
	XEmbeddedResource bool

	// x-kubernetes-int-or-string specifies that this value is
	// either an integer or a string. If this is true, an empty
	// type is allowed and type as child of anyOf is permitted
	// if following one of the following patterns:
	//
	// 1) anyOf:
	//    - type: integer
	//    - type: string
	// 2) allOf:
	//    - anyOf:
	//      - type: integer
	//      - type: string
	//    - ... zero or more
	XIntOrString bool

	// x-kubernetes-list-map-keys annotates lists with the x-kubernetes-list-type `map` by specifying the keys used
	// as the index of the map.
	//
	// This tag MUST only be used on lists that have the "x-kubernetes-list-type"
	// extension set to "map". Also, the values specified for this attribute must
	// be a scalar typed field of the child structure (no nesting is supported).
	XListMapKeys []string

	// x-kubernetes-list-type annotates a list to further describe its topology.
	// This extension must only be used on lists and may have 3 possible values:
	//
	// 1) `atomic`: the list is treated as a single entity, like a scalar.
	//      Atomic lists will be entirely replaced when updated. This extension
	//      may be used on any type of list (struct, scalar, ...).
	// 2) `set`:
	//      Sets are lists that must not have multiple items with the same value. Each
	//      value must be a scalar (or another atomic type).
	// 3) `map`:
	//      These lists are like maps in that their elements have a non-index key
	//      used to identify them. Order is preserved upon merge. The map tag
	//      must only be used on a list with elements of type object.
	XListType *string

	// x-kubernetes-map-type annotates an object to further describe its topology.
	// This extension must only be used when type is object and may have 2 possible values:
	//
	// 1) `granular`:
	//      These maps are actual maps (key-value pairs) and each fields are independent
	//      from each other (they can each be manipulated by separate actors). This is
	//      the default behaviour for all maps.
	// 2) `atomic`: the list is treated as a single entity, like a scalar.
	//      Atomic maps will be entirely replaced when updated.
	// +optional
	XMapType *string
