How do I change settings on the hyper client used by the SDK, such as pool idle timeout or other HTTP settings?

As of version 0.6.0 of the SDK, the hyper client settings can be customized by manually creating a connector with aws_smithy_client::hyper_ext::Builder:

// Load credentials from the environment as usual
let shared_config = aws_config::load_from_env().await;

// Create a connector with the underlying hyper client customized
let conn = aws_smithy_client::hyper_ext::Builder::default()
    .hyper_builder({
        let mut builder = hyper::Client::builder();
        // Customize the hyper client here with the builder methods on 
        // https://docs.rs/hyper/0.14.17/hyper/client/struct.Builder.html
        // For example:
        // builder.pool_idle_timeout(None);
        builder
    })
    // Use the default https connector
    .build(aws_smithy_client::conns::https());

// Create the AWS service client with the shared config and the customized connector
let client = Client::from_conf_conn((&shared_config).into(), conn);
