func NewErrorTypeMatcher Uses

❖
func NewErrorTypeMatcher(t ErrorType) utilerrors.Matcher

NewErrorTypeMatcher returns an errors.Matcher that returns true if the provided error is a Error and has the provided ErrorType.

type Error Uses

❖
type Error struct {
    Type     ErrorType
    Field    string
    BadValue interface{}
    Detail   string
}

Error is an implementation of the 'error' interface, which represents a field-level validation error.

func Duplicate Uses

❖
func Duplicate(field *Path, value interface{}) *Error

Duplicate returns a *Error indicating "duplicate value". This is used to report collisions of values that must be unique (e.g. names or IDs).

func Forbidden Uses

❖
func Forbidden(field *Path, detail string) *Error

Forbidden returns a *Error indicating "forbidden". This is used to report valid (as per formatting rules) values which would be accepted under some conditions, but which are not permitted by current conditions (e.g. security policy).

func InternalError Uses

❖
func InternalError(field *Path, err error) *Error

InternalError returns a *Error indicating "internal error". This is used to signal that an error was found that was not directly related to user input. The err argument must be non-nil.

func Invalid Uses

❖
func Invalid(field *Path, value interface{}, detail string) *Error

Invalid returns a *Error indicating "invalid value". This is used to report malformed values (e.g. failed regex match, too long, out of bounds).

func NotFound Uses

❖
func NotFound(field *Path, value interface{}) *Error

NotFound returns a *Error indicating "value not found". This is used to report failure to find a requested value (e.g. looking up an ID).

func NotSupported Uses

❖
func NotSupported(field *Path, value interface{}, validValues []string) *Error

NotSupported returns a *Error indicating "unsupported value". This is used to report unknown values for enumerated fields (e.g. a list of valid values).

func Required Uses

❖
func Required(field *Path, detail string) *Error

Required returns a *Error indicating "value required". This is used to report required values that are not provided (e.g. empty strings, null values, or empty arrays).

func TooLong Uses

❖
func TooLong(field *Path, value interface{}, maxLength int) *Error

TooLong returns a *Error indicating "too long". This is used to report that the given value is too long. This is similar to Invalid, but the returned error will not include the too-long value.

func TooMany Uses

❖
func TooMany(field *Path, actualQuantity, maxQuantity int) *Error

TooMany returns a *Error indicating "too many". This is used to report that a given list has too many items. This is similar to TooLong, but the returned error indicates quantity instead of length.

func (*Error) Error Uses

❖
func (v *Error) Error() string

Error implements the error interface.

func (*Error) ErrorBody Uses

❖
func (v *Error) ErrorBody() string

ErrorBody returns the error message without the field name. This is useful for building nice-looking higher-level error reporting.

type ErrorList Uses

❖
type ErrorList []*Error

ErrorList holds a set of Errors. It is plausible that we might one day have non-field errors in this same umbrella package, but for now we don't, so we can keep it simple and leave ErrorList here.

func (ErrorList) Filter Uses

❖
func (list ErrorList) Filter(fns ...utilerrors.Matcher) ErrorList

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

func (ErrorList) ToAggregate Uses

❖
func (list ErrorList) ToAggregate() utilerrors.Aggregate

ToAggregate converts the ErrorList into an errors.Aggregate.

type ErrorType Uses

❖
type ErrorType string

ErrorType 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 (
    // ErrorTypeNotFound is used to report failure to find a requested value
    // (e.g. looking up an ID).  See NotFound().
    ErrorTypeNotFound ErrorType = "FieldValueNotFound"
    // ErrorTypeRequired is used to report required values that are not
    // provided (e.g. empty strings, null values, or empty arrays).  See
    // Required().
    ErrorTypeRequired ErrorType = "FieldValueRequired"
    // ErrorTypeDuplicate is used to report collisions of values that must be
    // unique (e.g. unique IDs).  See Duplicate().
    ErrorTypeDuplicate ErrorType = "FieldValueDuplicate"
    // ErrorTypeInvalid is used to report malformed values (e.g. failed regex
    // match, too long, out of bounds).  See Invalid().
    ErrorTypeInvalid ErrorType = "FieldValueInvalid"
    // ErrorTypeNotSupported is used to report unknown values for enumerated
    // fields (e.g. a list of valid values).  See NotSupported().
    ErrorTypeNotSupported ErrorType = "FieldValueNotSupported"
    // ErrorTypeForbidden is used to report valid (as per formatting rules)
    // values which would be accepted under some conditions, but which are not
    // permitted by the current conditions (such as security policy).  See
    // Forbidden().
    ErrorTypeForbidden ErrorType = "FieldValueForbidden"
    // ErrorTypeTooLong is used to report that the given value is too long.
    // This is similar to ErrorTypeInvalid, but the error will not include the
    // too-long value.  See TooLong().
    ErrorTypeTooLong ErrorType = "FieldValueTooLong"
    // ErrorTypeTooMany is used to report "too many". This is used to
    // report that a given list has too many items. This is similar to FieldValueTooLong,
    // but the error indicates quantity instead of length.
    ErrorTypeTooMany ErrorType = "FieldValueTooMany"
    // ErrorTypeInternal is used to report other errors that are not related
    // to user input.  See InternalError().
    ErrorTypeInternal ErrorType = "InternalError"
)

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

func (ErrorType) String Uses

❖
func (t ErrorType) String() string

String converts a ErrorType into its corresponding canonical error message.

type Path Uses

❖
type Path struct {
    // contains filtered or unexported fields
}

Path represents the path from some root to a particular field.

func NewPath Uses

❖
func NewPath(name string, moreNames ...string) *Path

NewPath creates a root Path object.

func (*Path) Child Uses

❖
func (p *Path) Child(name string, moreNames ...string) *Path

Child creates a new Path that is a child of the method receiver.

func (*Path) Index Uses

❖
func (p *Path) Index(index int) *Path

Index indicates that the previous Path is to be subscripted by an int. This sets the same underlying value as Key.

func (*Path) Key Uses

❖
func (p *Path) Key(key string) *Path

Key indicates that the previous Path is to be subscripted by a string. This sets the same underlying value as Index.

func (*Path) Root Uses

❖
func (p *Path) Root() *Path

Root returns the root element of this Path.

func (*Path) String Uses

❖
func (p *Path) String() string

String produces a string representation of the Path.
