--------------------------------------
Assignee: Neville Dipale
> [Rust] [BREAKING] Lists should take Field instead of DataType
> -------------------------------------------------------------
>
> Key: ARROW-10261
> URL: https://issues.apache.org/jira/browse/ARROW-10261
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Integration, Rust
> Affects Versions: 1.0.1
> Reporter: Neville Dipale
> Assignee: Neville Dipale
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.0.0
>
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> There is currently no way of tracking nested field metadata on lists. For
> example, if a list's children are nullable, there's no way of telling just by
> looking at the Field.
> This causes problems with integration testing, and also affects Parquet
> roundtrips.
> I propose the breaking change of [Large|FixedSize]List taking a Field instead
> of Box<DataType>, as this will overcome this issue, and ensure that the Rust
> implementation passes integration tests.
> CC [~andygrove] [~jorgecarleitao] [~alamb] [~jhorstmann] ([~carols10cents]
> as this addresses some of the roundtrip failures).
> I'm leaning towards this landing in 3.0.0, as I'd love for us to have
> completed or made significant traction on the Arrow Parquet writer (and
> reader), and integration testing, by then.
