Functions

func FromObject

func FromObject(obj runtime.Object) error

FromObject generates an statusError from an api.Status, if that is the type of obj; otherwise, returns an error created by fmt.Errorf.

func IsAlreadyExists

func IsAlreadyExists(err error) bool

IsAlreadyExists determines if the err is an error which indicates that a specified resource already exists.

func IsConflict

func IsConflict(err error) bool

IsConflict determines if the err is an error which indicates the provided update conflicts.

func IsInvalid

func IsInvalid(err error) bool

IsInvalid determines if the err is an error which indicates the provided resource is not valid.

func IsNotFound

func IsNotFound(err error) bool

IsNotFound returns true if the specified error was created by NewNotFoundErr.

func NewAlreadyExists

func NewAlreadyExists(kind, name string) error

NewAlreadyExists returns an error indicating the item requested exists by that identifier.

func NewConflict

func NewConflict(kind, name string, err error) error

NewConflict returns an error indicating the item can't be updated as provided.

func NewInvalid

func NewInvalid(kind, name string, errs ErrorList) error

NewInvalid returns an error indicating the item is invalid and cannot be processed.

func NewNotFound

func NewNotFound(kind, name string) error

NewNotFound returns a new error which indicates that the resource of the kind and the name was not found.

func ValueOf

func ValueOf(t ValidationErrorType) string

Types

type ErrorList

type ErrorList util.ErrorList

ErrorList is a collection of errors. This does not implement the error interface to avoid confusion where an empty ErrorList would still be an error (non-nil). To produce a single error instance from an ErrorList, use the ToError() method, which will return nil for an empty ErrorList.

func (ErrorList) Prefix

func (list ErrorList) Prefix(prefix string) ErrorList

Prefix adds a prefix to the Field of every ValidationError in the list. Returns the list for convenience.

func (ErrorList) PrefixIndex

func (list ErrorList) PrefixIndex(index int) ErrorList

PrefixIndex adds an index to the Field of every ValidationError in the list. Returns the list for convenience.

func (ErrorList) ToError

func (list ErrorList) ToError() error

ToError converts an ErrorList into a "normal" error, or nil if the list is empty.

type ValidationError

type ValidationError struct {
	Type     ValidationErrorType
	Field    string
	BadValue interface{}
}

ValidationError is an implementation of the 'error' interface, which represents an error of validation.

func NewFieldDuplicate

func NewFieldDuplicate(field string, value interface{}) ValidationError

NewFieldDuplicate returns a ValidationError indicating "duplicate value"

func NewFieldInvalid

func NewFieldInvalid(field string, value interface{}) ValidationError

NewFieldInvalid returns a ValidationError indicating "invalid value"

func NewFieldNotFound

func NewFieldNotFound(field string, value interface{}) ValidationError

NewFieldNotFound returns a ValidationError indicating "value not found"

func NewFieldNotSupported

func NewFieldNotSupported(field string, value interface{}) ValidationError

NewFieldNotSupported returns a ValidationError indicating "unsupported value"

func NewFieldRequired

func NewFieldRequired(field string, value interface{}) ValidationError

NewFieldRequired returns a ValidationError indicating "value required"

func (ValidationError) Error

func (v ValidationError) Error() string

type ValidationErrorType

type ValidationErrorType string

ValidationErrorType is a machine readable value providing more detail about why a field is invalid. These values are expected to match 1-1 with CauseType in api/types.go.

const (
	// ValidationErrorTypeNotFound is used to report failure to find a requested value
	// (e.g. looking up an ID).
	ValidationErrorTypeNotFound ValidationErrorType = "FieldValueNotFound"
	// ValidationErrorTypeRequired is used to report required values that are not
	// provided (e.g. empty strings, null values, or empty arrays).
	ValidationErrorTypeRequired ValidationErrorType = "FieldValueRequired"
	// ValidationErrorTypeDuplicate is used to report collisions of values that must be
	// unique (e.g. unique IDs).
	ValidationErrorTypeDuplicate ValidationErrorType = "FieldValueDuplicate"
	// ValidationErrorTypeInvalid is used to report malformed values (e.g. failed regex
	// match).
	ValidationErrorTypeInvalid ValidationErrorType = "FieldValueInvalid"
	// ValidationErrorTypeNotSupported is used to report valid (as per formatting rules)
	// values that can not be handled (e.g. an enumerated string).
	ValidationErrorTypeNotSupported ValidationErrorType = "FieldValueNotSupported"
)

TODO: These values are duplicated in api/types.go, but there's a circular dep. Fix it.
