Remi Dettai created ARROW-10620:
-----------------------------------
Summary: [Rust][Parquet] move column chunk range logic to
metadata.rs
Key: ARROW-10620
URL: https://issues.apache.org/jira/browse/ARROW-10620
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Reporter: Remi Dettai
Getting the range of bytes of a column chunk inside a parquet file can be
useful for external crates (for instance if they want to pre-fetch the
columns), and is not completely obvious (it is enough to take a look at [1] and
[2] to see that things can quickly get messy).
I think it would be nice to move this logic in the metadata definition rather
than have lost it in the middle of the reader implem.
