v0.18.0

[Xuanwo]

Upgrade to v0.18

OpenDAL v0.18 introduces the following breaking changes:

• Deprecated feature flag services-http has been removed.
• All DirXxx items have been renamed to ObjectXxx to make them more consistent.
  • DirEntry -> ObjectEntry
  • DirStream -> ObjectStream
  • DirStreamer -> ObjectStream
  • DirIterate -> ObjectIterate
  • DirIterator -> ObjectIterator

Besides, we also make a big change to our ObjectEntry API. Since v0.18, we can fully reuse the metadata that fetched during list. Take entry.content_length() for example:

• If content_lenght is already known, we will return directly.
• If not, we will check if the object entry is complete:
  • If complete, the entry already fetched all metadata that it could have, return directly.
  • If not, we will send a stat call to get the metadata and refresh our cache.

This change means:

• All API like content_length will be changed into async functions.
• metadata and blocking_metadata will not return errors anymore.
• To retrieve the latest meta, please use entry.into_object().metadata() instead.
