funcNew¶

func New(errs ...error)error

New returns an error composed from errs.Some errors in errs get special treatment:

• nil errors are discarded
• errors of type Error are expanded into the top level

If the resulting slice has length 0, New returns nil.If the resulting slice has length 1, New returns that error.If the resulting slice has length > 1, New returns that slice as an Error.

funcRange¶added inv1.36.0

func Range(errerror, fn func(error)bool)bool

Range performs a pre-order, depth-first iteration of the error treeby successively unwrapping all error values.For each iteration it calls fn with the current error value andstops iteration if it ever reports false.

typeError¶

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

An Error represents multiple errors.

func (eError) As(targetany)bool

func (eError) Error()string

func (eError) Errors() []error

func (eError) Is(targeterror)bool

func (eError) Unwrap() []error
