How to get the Content-MD5 for a file?

[abitofhelp]

Hello,

I have a rust application that uses "azure_storage_datalake" at [https://github.com/ Azure/Azure-Sdk-for-rust][1]. The application can enumerate all of the files, and I can determine the name and size of each file. What I haven't been able to figure out is how to get the Content-MD5 for each file. I hope to get the value rather than having to scan each file and determine the MD5 values on the fly. The RESTful API that Azure provides shows the Content-MD5 can be determined,

https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/path/get-properties?view=rest-storageservices-datalakestoragegen2-2019-12-12

I'd appreciate any tips on how to get it using the "azure_storage_datalake" sdk.

Thank you for your time and interest.

Here is the code that I have been developing:

    let data_lake_client = DataLakeClient::new(
        self.account_name.to_owned(),
        self.storage_credentials.to_owned(),
    );

    let file_system_client = data_lake_client.file_system_client(container_name);
    let directory_client = file_system_client.clone().into_directory_client(".");

    let mut page_cnt = 0;
    let mut cnt = 0;
    let mut response = directory_client
        .list_paths()
        .directory("alm")
        .recursive(true)
        .max_results(NonZeroU32::new(paging_size).unwrap())
        .into_stream()
        .enumerate();

    loop {
        let page = response.next().await;

        match page {
            Some((_, p)) => match p {
                Ok(_) => {
                    page_cnt += 1;
                    let paths = p.unwrap().paths;
                    cnt += paths.len();
                    paths.iter().for_each(|b| {
                        if !b.is_directory {
                            println!("[{}/{}]: {}, Size: {} bytes, MD5: '{}'",
                                     page_cnt,
                                     cnt,
                                     b.name,
                                     b.content_length as u64,
                                     "tbd".to_string(),  // <<<<< How to get the ContentMD5 value for this file?
                            );
                        }
                    });
                }
                Err(e) => {
                    println!("{:#?}", e);
                    break;
                }
            },
            None => {
                break;
            }
        }
    }
