Types

type Errors

type Errors []error

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

func (*Errors) Append

func (*Errors) Error

func (e *Errors) Error() string

func (*Errors) ErrorOrNil

func (e *Errors) ErrorOrNil() error

ErrorOrNil returns an error interface if this Error represents a list of errors, or returns nil if the list of errors is empty. This function is useful at the end of accumulation to make sure that the value returned represents the existence of errors.
