Summary: [Rust] Refactor Rust API to use traits and generics (was: [Rust]
Review Array design before first release)
> [Rust] Refactor Rust API to use traits and generics
> ---------------------------------------------------
>
> Key: ARROW-2521
> URL: https://issues.apache.org/jira/browse/ARROW-2521
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Rust
> Reporter: Andy Grove
> Assignee: Andy Grove
> Priority: Major
> Fix For: 0.10.0
>
>
> Early on, [~kszucs] and I worked on two different designs for how to
> represent Arrow arrays in Rust, each with their pros and cons.
> Krisztian started out with a generics approach e.g. Array<T> which was great
> until we tried to implement structs, which can contain mixed types so we
> ended up using enum to represent arrays, which was great until I got to the
> list types ... I don't think I can implement nested lists with this approach.
> I am reviewing this again now that I am more familiar with Arrow and also my
> Rust skills have improved greatly since I started working on all of this.
> I will be prototyping in a separate repo, and will update this Jira once I
> have something concrete to share, but I feel it is important to address this
> before the first official release of the Rust version. Also, if we are going
> to consider a refactor like this, it is better to do it now while the
> codebase is tiny.
