Function dropbox_sdk::files::upload_session_start

pub fn upload_session_start(

) -> Result<Result<UploadSessionStartResult, UploadSessionStartError>>

This is supported on crate feature dbx_files only.

Upload sessions allow you to upload a single file in one or more requests, for example where the size of the file is greater than 150 MB. This call starts a new upload session with the given data. You can then use upload_session_append_v2() to add more data and upload_session_finish() to save all the data to a file in Dropbox. A single request should not upload more than 150 MB. The maximum size of a file one can upload to an upload session is 350 GB. An upload session can be used for a maximum of 7 days. Attempting to use an UploadSessionStartResult::session_id with upload_session_append_v2() or upload_session_finish() more than 7 days after its creation will return a UploadSessionLookupError::NotFound. Calls to this endpoint will count as data transport calls for any Dropbox Business teams with a limit on the number of data transport calls allowed per month. For more information, see the Data transport limit page. By default, upload sessions require you to send content of the file in sequential order via consecutive upload_session_start(), upload_session_append_v2(), upload_session_finish() calls. For better performance, you can instead optionally use a UploadSessionType::Concurrent upload session. To start a new concurrent session, set UploadSessionStartArg::session_type to UploadSessionType::Concurrent. After that, you can send file data in concurrent upload_session_append_v2() requests. Finally finish the session with upload_session_finish(). There are couple of constraints with concurrent sessions to make them work. You can not send data with upload_session_start() or upload_session_finish() call, only with upload_session_append_v2() call. Also data uploaded in upload_session_append_v2() call must be multiple of 4194304 bytes (except for last upload_session_append_v2() with UploadSessionStartArg::close to true, that may contain any remaining data).
