> https://github.com/apache/arrow/commit/7155cd5488310c15d864428252ca71dd9ebd3b48 Reworked how the parquet reader traits were implemented to be interms of a `ChunkReader` trait (for the better, in my opinion). 
> That commit includes two helper classes,  `SliceableCursor` and `FileSource`, which implement `ChunkReader` for a `Cursor` like thing and `File`s, respectively
> My project uses the parquet SerializedFileWriter with things that look like `File` and `Cursor` and thus I would like to re-use the logic in  `SliceableCursor` and `FileSource` without having to copy/paste them.
