I think I've finally got a working example that lists all Objects in a folder for a given bucket.

use google_cloud_auth::credentials::{Credentials,service_account::Builder};
use google_cloud_storage::client::{Storage,StorageControl};
use google_cloud_gax::paginator::ItemPaginator;

#[tokio::main]
async fn main() {
let gcloud_bucket_service_account=env::var("USER_UPLOADS_SERVICE_ACCOUNT").expect("Ahhhh PANIC! No Bucket Secret 🪣🤫");
    let json = serde_json::from_str(&gcloud_bucket_service_account).expect("Serde parse failed");
    let credentials = Builder::new(json).build().expect("🌈 : Failed GCloud Credential Object Generation");
    let client = StorageControl::builder().with_credentials(credentials).build().await.expect("🌈 : Failed GCloud Storage Control Generation");
    let list_obj_req_builder = client
        .list_objects()
        .set_parent("projects/_/buckets/<Your_Bucket_ID>")
        .set_prefix("<Some_Folder_Name>/");
    let mut items = list_obj_req_builder.by_item();
    while let Some(result) = items.next().await {
        let item = result;
        println!("{:?}",item);
    }

This took me a very long time to achieve. I even searched all public GH repos and the usage of this library seems very low (I gave up looking), I think with some proper examples you'd see a lot more adoption.

It looks like a lot of love/effort is being poured into this library (2k+ commits 👀) I plan to contribute some doc/example improvements in good faith as I integrate it into my back-end.

CC: @coryan may ping you in some questions here related to examples/docs if that's okay
