Function asNonContextError

lib/svcutil/svcutil.go:215–225

asNonContextError returns err, except if it is context.Canceled or context.DeadlineExceeded in which case the error will be a simple string representation instead. The given context is checked for cancellation, and if it is cancelled then that error is returned instead of err.
