merror

GoDoc Build Status

Multiple Error aggregator for Go.

Usage

func foo() error {
  merr := merror.New()

  if err := DoSomething(); err != nil {
    merr.Append(err)
  }

  return merr.ErrorOrNil()
}

A bounded merror can be used to guard against memory ballooning.

func bar() error {
  merr := merror.NewWithCap(10)

  for i := 0; i < 15; i++ {
    if err := DoSomething(); err != nil {
      merr.Append(err)
    }
  }

  fmt.Printf("Len: %d,  Overflow: %d", merr.Len(), merr.Overflow()) 
  // Len: 10,  Overflow: 5

  return merr.ErrorOrNil()
}

errors.Is

If any of the errors appended to a merror match the target error passed to errors.Is(err, target error) then true is returned.

errors.As

If any of the errors appended to a merror match the target type passed to errors.As(err error, target any) then true is returned and the target is set to the matching error.
