re-export of aws-smithy-types in dynamodb sdk

[pdeva]

the readme for aws-smithy-types says:

Generally, you should not need to take a direct dependency   
on this crate as service clients should publicly re-export the types when used.

However, in AttributeValue, to pass a Blob object, one will indeed need to take a dependency on aws-smithy-types.

is this something that needs to be fixed in the dynamodb sdk or am i using it incorrectly somehow by depending on aws-smithy-types ?

Blob is in the primitives module in aws-sdk-dynamodb: https://docs.rs/aws-sdk-dynamodb/latest/aws_sdk_dynamodb/primitives/struct.Blob.html

ah i see.

so i explored a bit more, and i notice that i dont see re-export of ::aws_smithy_runtime_api::client::result::SdkError or ::aws_smithy_runtime_api::client::orchestrator::HttpResponse anywhere.

so for example, handling the result of transactWriteItems.send() cannot be done without depending on aws-smithy-runtime-api , which the Readme for it also says shouldnt be needed.

[jdisanti]

SdkError is re-exported: https://docs.rs/aws-sdk-dynamodb/latest/aws_sdk_dynamodb/error/type.SdkError.html

Make sure you're searching the crate's docs in docs.rs for these. They should come right up.

What do you need HttpResponse for? It should only be needed if you're writing interceptors or other special use-cases.

[pdeva]

got it. yeah i think HttpResponse was just used cause it was part of the result generic type. i managed to get rid of it.
