How do you download a directory with S3?

[garrettmaring]

When attempting to download a directory and invoke put_object with that body, the following error is returned:

Error: ServiceError { err: GetObjectError { kind: NoSuchKey(NoSuchKey), meta: Error { code: Some("NoSuchKey"), message: Some("The specified key does not exist.")

This is using the sample code https://github.com/awslabs/aws-sdk-rust/blob/main/sdk/examples/s3-helloworld/src/main.rs.

    let resp = client
        .get_object()
        .bucket(BUCKET)
        .key("my-directory/")
        .send();

When downloading a single file, it works as expected.

I'm using list_objects (should I use v2?) and get_object to get the job done fine for now.

yeah that's correct. Downloading an entire with the SDK isn't actually supported by the core clients, the Rust SDK only supports downloading single files. SDK's that support entire directories do so with a "high level library" like "S3 Transfer Manager." We don't have that HLL for Rust yet.

And re: list_objects vs. list_objects_v2, v2 adds support for pagination.
