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: config.rs
    path of file: ./repos/aws-sdk-rust/sdk/ssmcontacts/src
    
    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.

/// Configuration for a aws_sdk_ssmcontacts service client.
///
///
/// Service configuration allows for customization of endpoints, region, credentials providers,
/// and retry configuration. Generally, it is constructed automatically for you from a shared
/// configuration loaded by the `aws-config` crate. For example:
///
/// ```ignore
/// // Load a shared config from the environment
/// let shared_config = aws_config::from_env().load().await;
/// // The client constructor automatically converts the shared config into the service config
/// let client = Client::new(&shared_config);
/// ```
