Available on crate feature
async only.初始化的异步分片信息
Required Methods
sourcefn new<R: ResumableRecorder<HashAlgorithm = Self::HashAlgorithm> + 'static>(
upload_manager: UploadManager,
resumable_recorder: R
) -> Self
fn new<R: ResumableRecorder<HashAlgorithm = Self::HashAlgorithm> + 'static>(
upload_manager: UploadManager,
resumable_recorder: R
) -> Self
创建分片上传器
sourcefn upload_manager(&self) -> &UploadManager
fn upload_manager(&self) -> &UploadManager

重新初始化分片信息
该步骤负责将先前已经初始化过的分片信息全部重置,清空断点续传记录器中的记录,之后从头上传整个文件
该方法的异步版本为 Self::async_reinitialize_parts。
sourcefn try_to_resume_parts<D: DataSource<Self::HashAlgorithm> + 'static>(
&self,
source: D,
params: ObjectParams
) -> Option<Self::InitializedParts>
fn try_to_resume_parts<D: DataSource<Self::HashAlgorithm> + 'static>(
&self,
source: D,
params: ObjectParams
) -> Option<Self::InitializedParts>
尝试恢复记录
如果提供了有效的断点续传记录器,该方法可以尝试在找到记录,如果找不到记录,或记录无法读取,则返回 None。
该方法的异步版本为 [Self::try_to_async_resume_records]。
sourcefn async_initialize_parts<D: AsyncDataSource<Self::HashAlgorithm> + 'static>(
&self,
source: D,
params: ObjectParams
) -> BoxFuture<'_, ApiResult<Self::AsyncInitializedParts>>
fn async_initialize_parts<D: AsyncDataSource<Self::HashAlgorithm> + 'static>(
&self,
source: D,
params: ObjectParams
) -> BoxFuture<'_, ApiResult<Self::AsyncInitializedParts>>
Available on crate feature
async only.异步初始化分片信息
该步骤只负责初始化分片,但不实际上传数据,如果提供了有效的断点续传记录器,则可以尝试在这一步找到记录。
sourcefn async_upload_part<'r>(
&'r self,
initialized: &'r Self::AsyncInitializedParts,
data_partitioner_provider: &'r dyn DataPartitionProvider

initialized: &'r Self::AsyncInitializedParts,
data_partitioner_provider: &'r dyn DataPartitionProvider
) -> BoxFuture<'r, ApiResult<Option<Self::AsyncUploadedPart>>>
Available on crate feature
async only.异步上传分片
实际上传的分片大小由提供的分片大小提供者获取。
如果返回 [Ok(None)] 则表示已经没有更多分片可以上传。
