How to determine VPC an RDS instance is associated to?

It looks to me that aws_sdk_rds::types::_db_cluster does not contain that while the info vpc_security_groups is available.

You should be able to get this with VpcSecurityGroupMembership (and DbSubnetGroup will have even more info)

It would look like this:

let client = aws_sdk_rds::Client::new(&config);
let result = client.describe_db_instances().send.await?; 
//optionally pass db_instance_identifier or filters (https://docs.rs/aws-sdk-rds/latest/aws_sdk_rds/operation/describe_db_instances/struct.DescribeDbInstancesInput.html)

for db_instance in result.db_instances().unwrap_or_default() {
    println!(
        "DB security groups: {:?}",
        db_instance
            .vpc_security_groups().unwrap_or_default().vpc_security_group_id().unwrap()
            .expect("instance should have a security group")
    );
    println!(
        "DB subnet group:    {:?}",
        db_instance
            .db_subnet_group().unwrap_or_default().db_subnet_group_name().unwrap()
            .expect("instance should a subnet group")
    );
}

I just found that pub fn db_subnet_group(&self) -> ::std::option::Option<&str> does not return a struct DbSubnetGroup and VpcSecurityGroupMembership only has vpc_security_group_id and has status.

Edit: I may need to use https://docs.rs/aws-sdk-rds/latest/aws_sdk_rds/operation/describe_db_subnet_groups/struct.DescribeDbSubnetGroupsOutput.html#method.db_subnet_groups
