Module opendal::raw::oio

oio provides OpenDAL’s raw traits and types that opendal returns as output.

Those types should only be used internally and we don’t want users to depend on them.

Structs

• AppendWriter
  AppendWriter will implements oio::Write based on append object.
• BatchDeleteResult
  BatchDeleteResult is the result of batch delete operation.
• BatchDeleter
  BatchDeleter is used to implement oio::Delete based on batch delete.
• BlockWriter
  BlockWriter will implements oio::Write based on block uploads.
• Entry
  Entry is returned by Page or BlockingPage during list operations.
• FlatLister
  FlatLister will walk dir in bottom up way:
• FlexBuf
  FlexBuf is a buffer that support frozen bytes and reuse existing allocated memory.
• HierarchyLister
  ToHierarchyLister will convert a flat list to hierarchy by filter not needed entries.
• MultipartPart
  The result of MultipartWrite::write_part.
• MultipartWriter
  MultipartWriter will implements oio::Write based on multipart uploads.
• OneShotDeleter
  OneShotDelete is used to implement oio::Delete based on one shot.
• OneShotWriter
  OneShotWrite is used to implement oio::Write based on one shot.

  PageContext is the context passing between PageList.
• PageLister
  PageLister implements oio::List based on PageList.
• PooledBuf
  PooledBuf is a buffer pool that designed for reusing already allocated bufs.
• PositionWriter
  PositionWriter will implements oio::Write based on position write.
• PrefixLister
  PrefixLister is used to filter entries by prefix.
• QueueBuf
  QueueBuf is a queue of Buffer.

Traits

• AppendWrite
  AppendWrite is used to implement oio::Write based on append object. By implementing AppendWrite, services don’t need to care about the details of buffering and uploading parts.
• BatchDelete
  BatchDelete is used to implement oio::Delete based on batch delete operation.
• BlockWrite
  BlockWrite is used to implement oio::Write based on block uploads. By implementing BlockWrite, services don’t need to care about the details of uploading blocks.
• BlockingDelete
  BlockingDelete is the trait to perform delete operations.
• BlockingList
  BlockingList is the blocking version of List.
• BlockingOneShotDelete
  BlockingOneShotDelete is used to implement oio::BlockingDelete based on one shot operation.
• BlockingRead
  Read is the trait that OpenDAL returns to callers.
• BlockingWrite
  BlockingWrite is the trait that OpenDAL returns to callers.
• Delete
  The Delete trait defines interfaces for performing deletion operations.
• DeleteDyn
  The dyn version of Delete
• List
  Page trait is used by raw::Accessor to implement list operation.
• MultipartWrite
  MultipartWrite is used to implement oio::Write based on multipart uploads. By implementing MultipartWrite, services don’t need to care about the details of uploading parts.
• OneShotDelete
  OneShotDelete is used to implement oio::Delete based on one shot operation.
• OneShotWrite
  OneShotWrite is used to implement oio::Write based on one shot operation. By implementing OneShotWrite, services don’t need to care about the details.
• PageList
  PageList is used to implement oio::List based on API supporting pagination. By implementing PageList, services don’t need to care about the details of page list.
• PositionWrite
  PositionWrite is used to implement oio::Write based on position write.
• Read
  Read is the internal trait used by OpenDAL to read data from storage.
• ReadDyn
  ReadDyn is the dyn version of Read make it possible to use as Box<dyn ReadDyn>.
• Write
  Write is the trait that OpenDAL returns to callers.
