> I also don't really follow the vague interface design that @tustvold
proposes here
As a very first cut one could take your existing implementation that yields
a stream and wrap it up as follows
```
pub struct ChunkedDownloader {}
impl ChunkedDownloader {
pub fn new(store: Arc<dyn ObjectStore>, meta: &ObjectMeta) -> Self {
... }
pub fn with_chunk_size() {...}
pub fn with_max_concurrency() {...}
pub fn into_stream(self) -> impl Stream<Result<Bytes>>
}
```
One could in future envision extending that with additional functionality,
for example
```
pub async fn sink<W: AsyncWrite + AsyncSeek>(self, out: W) -> Result<()>
{...}
pub fn into_unordered_stream(self) -> impl Stream<Result<(u64, Bytes)>>
```
