Would have been nice to have serde_dynamo's feature within aws-sdk-dynamodb

[Salman-Sali]

Describe the feature

aws_lambda_events currently uses serde_dynamo's AttributeValue types instead of aws-sdk-dynamodb's. Why don't aws-sdk-dynamodb introduce serde_dynamo's code in inself, so that aws_lambda_events can deserailize the stream.

Use Case

Right now its annoying to have to handle two types.

Proposed Solution

No response

Other Information

Maybe its serde_dynamo who should use aws-sdk-dynamodb's AttributeValue?

Unfortunately, separate types are required at this point, as the underlying types from aws-sdk-dynamodb do not support Serialize/Deserialize out of the box. The reason for this, as well as why aws-sdk-dynamodb is not introducing the serde_dynamo implementation itself, is explained here (still relevant today).

That being said, a design has been discussed to address this problem space.
