pub struct Download<'a, Request, Response> { /* private fields */ }Expand description
An ongoing download.
Note that this does not necessarily result in a download. It is returned by all API methods
that are capable of downloading data. Whether a download takes place is determined by the
Content-Type sent by the server; frequently, the parameters sent in the request determine
whether the server starts a download (Content-Type: whatever) or sends a response
(Content-Type: application/json).
Implementations§
Source§impl<'a, Request: Serialize + Debug, Response: DeserializeOwned + Debug> Download<'a, Request, Response>
impl<'a, Request: Serialize + Debug, Response: DeserializeOwned + Debug> Download<'a, Request, Response>
Sourcepub async fn do_it_to_buf(
&mut self,
buf: &mut Vec<u8>,
) -> Result<DownloadResult<Response>>
pub async fn do_it_to_buf( &mut self, buf: &mut Vec<u8>, ) -> Result<DownloadResult<Response>>
Trivial adapter for download(): Store downloaded data into a Vec<u8>.
Sourcepub async fn do_it(
&mut self,
dst: Option<&mut dyn AsyncWriteUnpin>,
) -> Result<DownloadResult<Response>>
pub async fn do_it( &mut self, dst: Option<&mut dyn AsyncWriteUnpin>, ) -> Result<DownloadResult<Response>>
Run the actual download, streaming the response into the supplied dst. If the server
responded with a Response object, no download is started; the response is wrapped in the
DownloadResult<Response> object.
Whether a download takes place or you receive a structured Response (i.e. a JSON object)
depends on the Content-Type sent by the server. It is an error to attempt a download
without specifying dst. Often, whether a download takes place is influenced by the
request parameters. For example, alt = media is frequently used in Google APIs to
indicate that a download is expected.
