multierror

Go package implementing an error that can contain multiple errors

multierror wraps multiple errors into a typed slice that implements Go's error interface. It's useful for iterators that don't bail when they encounter an error, but still need to return error information to the caller.

multierror.MultiError aims toward leanness and is mainly utilized with a combination of error and slice semantics.
