You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: _outpost_config_response.rs
    path of file: ./repos/aws-sdk-rust/sdk/eks/src/types
    
    the code of the file until where you have to start completion: // Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.

/// <p>An object representing the configuration of your local Amazon EKS cluster on an Amazon Web Services Outpost. This API isn't available for Amazon EKS clusters on the Amazon Web Services cloud.</p>
