Upgrade to v0.20

v0.20 is a big release that we introduce a lot of performance related changes.

To make the best of information from read operation, we propose and implemented RFC-0926: Object Reader. By this RFC, we can fetch content length from ObjectReader now!

pub struct ObjectReader {
    inner: BytesReader
    meta: ObjectMetadata,
}

impl ObjectReader {
    pub fn content_length(&self) -> u64 {}
    pub fn last_modified(&self) -> Option<OffsetDateTime> {}
    pub fn etag(&self) -> Option<String> {}
}

To make this happen, we changed our Accessor API:

- async fn read(&self, path: &str, args: OpRead) -> Result<BytesReader> {}
+ async fn read(&self, path: &str, args: OpRead) -> Result<ObjectReader> {}

All layers should be updated to meet this change. Also, it's required to return content_length while building ObjectReader. Please make sure the returning ObjectMetadata is used correctly.
