Instance Variable index The index of the Deferred in the DeferredList where it happened. (type: int)
Method __init__ Undocumented
Method __repr__ The repr of FirstError instances includes the repr of the wrapped failure's exception and the index of the FirstError.
Method __str__ The str of FirstError instances includes the str of the entire wrapped failure (including its traceback and exception) and the index of the FirstError.
Method __cmp__ No summary
