===================

**New this release:**

- :tada: (all, [smithy-rs#3173](https://github.com/awslabs/smithy-rs/issues/3173), [smithy-rs#3171](https://github.com/awslabs/smithy-rs/issues/3171)) Enable conversion from `BuildError` into `SdkError` & `<service>::Error`. This allows customers to write the following code:

    ```rust

    async fn do_a_thing(client: &Client) -> Result<SdkError<SomeOperationError>> {

        client.run_operation().complex_field(ComplexField::builder()

            .a("a")

            .b("b")

            .build()?

        ).send().await?;

    }

    ```

    Previously, `?` could not be used in this position.
