if string slice is empty the following error is returned by the DynamoDB api when using the StringSliceMarsher:

operation error DynamoDB: PutItem, https response error StatusCode: 400, RequestID: QFEHV7VI05AS0PGUEKHHM9QQVVVV4KQNSO5AEMVJF66Q9ASUAAJG, api error ValidationException: One or more parameter values were invalid: An string set  may not be empty

• change Client type to Session and incorporate context for multiple api operations to share

SplitScanIntoSegments has a bug where all scan segments have the same segment #

This code should all use uint32 types not int32 types

// UnmarshalUint32 unmarshals an AttributeValue into the given value
func UnmarshalUint32(av ddb.AttributeValue, v *int32) error {
	return UnmarshalUint32Ptr(av, &v)
}

// Uint32PtrUnmarshaler returns a UnmarshalerFunc func that will unmarshal an AttributeValue into the given ptr
func Uint32PtrUnmarshaler(v **int32) UnmarshalerFunc {
	return func(av ddb.AttributeValue) error {
		return UnmarshalUint32Ptr(av, v)
	}
}

// Uint32Unmarshaler returns a UnmarshalerFunc func that will unmarshal an AttributeValue into the given ptr
func Uint32Unmarshaler(v *int32) UnmarshalerFunc {
	return func(av ddb.AttributeValue) error {
		return UnmarshalUint32(av, v)
	}
}

May be important to be able to have basic type marshalers have another NilMode of NilError available to force an error to be thrown if that value is nil

readme needs to be updated to be accurate for latest version v0.2.11

• promises should have a state property that is exported to allow callers to know the state of the promise, either: pending, waiting for a response, or response ready
• promises should panic or return an error if Await is called before an operation is invoked or the promise is in pending state as this will block forever
