> [Rust] Support read:write of Feather files
> ------------------------------------------
>
> Key: ARROW-4463
> URL: https://issues.apache.org/jira/browse/ARROW-4463
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust
> Affects Versions: 0.12.0
> Reporter: Neville Dipale
> Assignee: Neville Dipale
> Priority: Major
> Labels: pull-request-available
> Time Spent: 40m
> Remaining Estimate: 0h
>
> As an Arrow developer/user, I'd like to be able to read and write Feather
> files.
> The current I/O story in Rust isn't great, we don't yet fully support reading
> and writing between Parquet, we can only read CSV but not yet writing. This
> is an inconvenience (at least for me).
> I propose supporting the Feather format in Rust, initially with the following
> limitations:
> * No date/time support until ARROW-4386 (and potentially more work) lands
> * Reading categorical data (from other languages) but not writing them
> * Reading and writing from and to single record batches. We don't yet
> support slicing of arrays ARROW-3954
> If the above are accept(ed|able), we can enhance the Feather support as the
> dependencies on the above limitations are lifted.
> We can also refactor the Feather code as we work on more IPC in Rust.
