README ¶

errors

errors provides utility routines for working with errors that are compatible with go 1.13+.

It currently provides:

errors.M which can be used to store multiple error values. errors.M is thread safe.

errs := errors.M{}
...
errs.Append(fn(a))
...
errs.Append(fn(b))
...
err := errs.Err()

Functions ¶

func As ¶

func As(err error, target interface{}) bool

As calls errors.As.

func Is ¶

func Is(err, target error) bool

Is calls errors.Is.

func New ¶

func New(m string) error

New calls errors.New.

func Unwrap ¶

func Unwrap(err error) error

Unwrap calls errors.Unwrap.

Types ¶

type M ¶

type M struct {
	// contains filtered or unexported fields
}

M represents multiple errors. It is thread safe. Typical usage is:

errs := errors.M{} ... errs.Append(err) ... return errs.Err()

func (*M) Append ¶

func (m *M) Append(errs ...error)

Append appends the specified errors excluding nil values.

func (*M) As ¶

func (m *M) As(target interface{}) bool

As supports errors.As.

func (*M) Clone ¶

func (m *M) Clone() *M

Clone returns a new errors.M that contains the same errors as itself.

func (*M) Err ¶

func (m *M) Err() error

Err returns nil if m contains no errors, or itself otherwise.

func (*M) Error ¶

func (m *M) Error() string

Error implements error.error

func (*M) Format ¶

func (m *M) Format(f fmt.State, c rune)

Format implements fmt.Formatter.Format.

func (*M) Is ¶

func (m *M) Is(target error) bool

Is supports errors.Is.

func (*M) Unwrap ¶

func (m *M) Unwrap() error

Unwrap implements errors.Unwrap. It returns the first stored error and then removes that error.
