Functions

func Append

func Append(err error, errs ...error) error

Append is a helper function that will append more errors onto an List in order to create a larger multi-error.

If err is not a errors.List, then it will be turned into one. If any of the errs are errors.List, they will be flattened one level into err.

func NewMissingFieldError

func NewMissingFieldError(name string) error

func Wrap

func Wrap(err error, name string) error

func WrapIndex

func WrapIndex(err error, name string, index int) error

func WrapPath

func WrapPath(err error, name string, path string) error

Types

type Error

type Error struct {
	Target []Level
	Err    error
	Path   string
}

func (*Error) Error

func (e *Error) Error() string

func (*Error) Unwrap

func (e *Error) Unwrap() error

func (*Error) XPath

func (e *Error) XPath() string

type Level

type Level struct {
	Name  string
	Index int // -1 if not needed
}

func (*Level) String

func (l *Level) String() string

type List

type List struct {
	Errors []error
}

List is an error type to track multiple errors. This is used to accumulate errors in cases and return them as a single "error".

func (*List) Error

func (e *List) Error() string

func (*List) Len

func (e *List) Len() int

func (*List) Less

func (e *List) Less(i, j int) bool

func (*List) Swap

func (e *List) Swap(i, j int)

func (*List) Unwrap

func (e *List) Unwrap() error

Unwrap returns the first error of the chain if not empty.

type MissingFieldError

type MissingFieldError struct {
	Name string
}

func (*MissingFieldError) Error

func (e *MissingFieldError) Error() string

type ParseAttrError

type ParseAttrError struct {
	Name     string
	Required bool
}

func NewParseAttrError

func NewParseAttrError(name string, required bool) *ParseAttrError

func (*ParseAttrError) Error

func (e *ParseAttrError) Error() string
