 // This file contains types which are mirrors/duplicates of the upstream SDK
 // types. This exists so that users can depend solely on this wrapper library
 // without necessarially needing an SDK implementation present.
 //
 // This was done (instead of type-aliasing from the github version of the SDK)
 // because some of the types need to be tweaked (like Task.RetryOptions) to
 // interact well with the wrapper, and the inconsistency of having some types
 // defined by the gae package and others defined by the SDK was pretty awkward.
