use azure_core::http::RequestContent;

let data = b"hello world";
blob_client
    .upload(
        RequestContent::from(data.to_vec()),
        false,  // overwrite
        u64::try_from(data.len())?,
        None,
    )
    .await?;

Download Blob

let response = blob_client.download(None).await?;
let content = response.into_body().collect_bytes().await?;
println!("Content: {:?}", content);

Get Blob Properties

let properties = blob_client.get_properties(None).await?;
println!("Content-Length: {:?}", properties.content_length);
