/// Service configuration allows for customization of endpoints, region, credentials providers,

/// configuration loaded by the `aws-config` crate. For example:
///
/// ```ignore

/// 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);
/// ```
///
/// The service config can also be constructed manually using its builder.
