Cross-service types for AWS SDKs. Generally, types in this module will be re-exported by either specific service clients
or [`aws-config`](https://crates.io/crates/aws-config).
This crate is part of the [AWS SDK for Rust](https://awslabs.github.io/aws-sdk-rust/) and the [smithy-rs](https://github.com/awslabs/smithy-rs) code generator. In most cases, it should not be used directly.
