Current Network Resource Stub Semantics

App Runner exposes VPC-aware operations in the model but currently does not persist any networking resource state.

• CreateVpcConnector, DescribeVpcConnector, ListVpcConnectors, and DeleteVpcConnector return 501 NotImplemented.
• CreateVpcIngressConnection, DescribeVpcIngressConnection, ListVpcIngressConnections, UpdateVpcIngressConnection, and DeleteVpcIngressConnection also return 501 NotImplemented.
• No VPC connector, subnet, security group, ingress connection, or PrivateLink-style state is created in Winterbaume.
• The implementation does not consult winterbaume-ec2 state for these identifiers, so it does not check that referenced VPCs, subnets, security groups, VPC endpoints, network interfaces, or load balancers exist, belong to the same VPC, or are in a usable lifecycle state.

Example

use aws_sdk_apprunner::config::BehaviorVersion;
use winterbaume_apprunner::AppRunnerService;
use winterbaume_core::MockAws;

#[tokio::main]
async fn main() {
    let mock = MockAws::builder()
        .with_service(AppRunnerService::new())
        .build();

    let config = aws_config::defaults(BehaviorVersion::latest())
        .http_client(mock.http_client())
        .credentials_provider(mock.credentials_provider())
        .region(aws_sdk_apprunner::config::Region::new("us-east-1"))
        .load()
        .await;

    let client = aws_sdk_apprunner::Client::new(&config);

    let resp = client
        .list_services()
        .send()
        .await
        .expect("list_services should succeed");
    println!("App Runner services: {}", resp.service_summary_list().len());
}
