Labels: pull-request-available (was: )
> [Rust] Add support to produce a C Data interface
> ------------------------------------------------
>
> Key: ARROW-10109
> URL: https://issues.apache.org/jira/browse/ARROW-10109
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust
> Reporter: Jorge Leitão
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.0.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The goal of this issue is to support producing C Data arrays of Rust.
> The use-case that motivated this issue was the possibility of running
> DataFusion from Python and support moving arrays from DataFusion to
> Python/Pyarray and vice-versa.
> In particular, so that users can write Python UDFs that expect arrow arrays
> and return arrow arrays, in the same spirit as pandas-udfs in Spark work for
> Pandas.
> The brute-force way of writing these arrays is by converting element by
> element from and to native types. The efficient way of doing it to pass the
> memory address from and to each implementation, which is zero-copy.
> To support the latter, we need an FFI implementation in Rust that produces
> and consumes [C's Data
> interface|https://arrow.apache.org/docs/format/CDataInterface.html]
