    /// Constructs a fluent builder for the [`ListGatewayInstances`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder) operation.
    /// This operation supports pagination; See [`into_paginator()`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder::into_paginator).
    ///
    /// - The fluent builder is configurable:
    ///   - [`filter_arn(impl Into<String>)`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder::filter_arn) / [`set_filter_arn(Option<String>)`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder::set_filter_arn):<br>required: **false**<br>Filter the list results to display only the instances associated with the selected Gateway Amazon Resource Name (ARN).<br>
    ///   - [`max_results(i32)`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder::max_results) / [`set_max_results(Option<i32>)`](crate::operation::list_gateway_instances::builders::ListGatewayInstancesFluentBuilder::set_max_results):<br>required: **false**<br>The maximum number of results to return per API request. For example, you submit a ListInstances request with MaxResults set at 5. Although 20 items match your request, the service returns no more than the first 5 items. (The service also returns a NextToken value that you can use to fetch the next batch of results.) The service might return fewer results than the MaxResults value. If MaxResults is not included in the request, the service defaults to pagination with a maximum of 10 results per page.<br>

For example, you submit a ListInstances request with MaxResults set at 5. The service returns the first batch of results (up to 5) and a NextToken value. To see the next batch of results, you can submit the ListInstances request a second time and specify the NextToken value.<br>
