func NewTimeoutError added in v0.11.0 

func NewTimeoutError(message string) error

NewTimeoutError returns an error indicating that a timeout occurred before the request could be completed. Clients may retry, but the operation may still complete.

func NewValidationErrorFieldPrefixMatcher added in v0.11.0 

func NewValidationErrorFieldPrefixMatcher(prefix string) errors.Matcher

NewValidationErrorFieldPrefixMatcher returns an errors.Matcher that returns true if the provided error is a ValidationError and has a field with the provided prefix.

Types

type StatusError added in v0.6.0 

type StatusError struct {
	ErrStatus api.Status
}

StatusError is an error intended for consumption by a REST API server; it can also be reconstructed by clients from a REST response. Public to allow easy type switches.

func (*StatusError) Error added in v0.6.0 

func (e *StatusError) Error() string

Error implements the Error interface.

func (*StatusError) Status added in v0.6.0 

func (e *StatusError) Status() api.Status

Status allows access to e's status without having to know the detailed workings of StatusError. Used by pkg/apiserver.

type UnexpectedObjectError added in v0.6.0 

type UnexpectedObjectError struct {
	Object runtime.Object
}

UnexpectedObjectError can be returned by FromObject if it's passed a non-status object.

func (*UnexpectedObjectError) Error added in v0.6.0 

func (u *UnexpectedObjectError) Error() string

Error returns an error message describing 'u'.

type ValidationError 

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

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 NewFieldForbidden added in v0.5.1 

func NewFieldForbidden(field string, value interface{}) *ValidationError

NewFieldForbidden returns a *ValidationError indicating "forbidden"

func NewFieldInvalid 

func NewFieldInvalid(field string, value interface{}, detail string) *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" TODO: remove "value"

func NewFieldTooLong added in v0.13.0 

func NewFieldTooLong(field string, value interface{}) *ValidationError

func (*ValidationError) Error 

func (v *ValidationError) Error() string

type ValidationErrorList added in v0.5.1 

type ValidationErrorList []error

func (ValidationErrorList) Filter added in v0.11.0 

func (list ValidationErrorList) Filter(fns ...errors.Matcher) ValidationErrorList

Filter removes items from the ValidationErrorList that match the provided fns.

func (ValidationErrorList) Prefix added in v0.5.1 

func (list ValidationErrorList) Prefix(prefix string) ValidationErrorList

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

func (ValidationErrorList) PrefixIndex added in v0.5.1 

func (list ValidationErrorList) PrefixIndex(index int) ValidationErrorList

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

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"
	// ValidationErrorTypeForbidden is used to report valid (as per formatting rules)
	// values which would be accepted by some api instances, but which would invoke behavior
	// not permitted by this api instance (such as due to stricter security policy).
	ValidationErrorTypeForbidden ValidationErrorType = "FieldValueForbidden"
	// ValidationErrorTypeTooLong is used to report that given value is too long.
	ValidationErrorTypeTooLong ValidationErrorType = "FieldValueTooLong"
)

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

func (ValidationErrorType) String added in v0.9.0 

func (t ValidationErrorType) String() string

String converts a ValidationErrorType into its corresponding error message.
