Functions ¶
func ListFormatFunc ¶
ListFormatFunc is a basic formatter that outputs the number of errors that occurred along with a bullet point list of the errors.
func NotifyInterrupt ¶
func Promise ¶
func Promise(f PromiseFunc) chan error
Promise is a basic promise implementation: it wraps calls a function in a goroutine, and returns a channel which will later return the function's return value.
Types ¶
type ErrorFormatFunc ¶
ErrorFormatFunc is a function callback that is called by Error to turn the list of errors into a string.
type MultiError ¶
type MultiError struct {
Errors []error
ErrorFormat ErrorFormatFunc
}
MultiError is an error type to track multiple errors. This is used to accumulate errors in cases and return them as a single "error".
func AppendMulti ¶
func AppendMulti(err error, errs ...error) *MultiError
AppendMulti is a helper function that will append more errors onto an Error in order to create a larger multi-error.
If err is not a multierror.Error, then it will be turned into one. If any of the errs are multierr.Error, they will be flattened one level into err.
func (*MultiError) Error ¶
func (e *MultiError) Error() string
func (*MultiError) ErrorOrNil ¶
func (e *MultiError) 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.
func (*MultiError) GoString ¶
func (e *MultiError) GoString() string
func (*MultiError) WrappedErrors ¶
func (e *MultiError) WrappedErrors() []error
WrappedErrors returns the list of errors that this Error is wrapping. It is an implementatin of the errwrap.Wrapper interface so that multierror.Error can be used with that library.
This method is not safe to be called concurrently and is no different than accessing the Errors field directly. It is implementd only to satisfy the errwrap.Wrapper interface.
type PromiseFunc ¶
type PromiseFunc func() error
