[jira] [Created] (ARROW-12317) [Rust] JSON writer does not support
time, date or interval types
Andrew Lamb created ARROW-12317:
-----------------------------------
Summary: [Rust] JSON writer does not support time, date or interval types
Key: ARROW-12317
URL: https://issues.apache.org/jira/browse/ARROW-12317
Project: Apache Arrow
Issue Type: Improvement
Components: Rust
Reporter: Andrew Lamb
While working on https://issues.apache.org/jira/browse/ARROW-12267 , adding support for writing Timestamp types, I noticed we were also lacking support for other time types. Specifically, if you try to write an array with any of the following types as JSON it will panic:
An example of adding support for timestamps is on https://github.com/apache/arrow/pull/9968
```
pub type Date32Array = PrimitiveArray<Date32Type>;
pub type Date64Array = PrimitiveArray<Date64Type>;
pub type Time32SecondArray = PrimitiveArray<Time32SecondType>;
pub type Time32MillisecondArray = PrimitiveArray<Time32MillisecondType>;
pub type Time64MicrosecondArray = PrimitiveArray<Time64MicrosecondType>;
pub type Time64NanosecondArray = PrimitiveArray<Time64NanosecondType>;
pub type IntervalYearMonthArray = PrimitiveArray<IntervalYearMonthType>;
pub type IntervalDayTimeArray = PrimitiveArray<IntervalDayTimeType>;
pub type DurationSecondArray = PrimitiveArray<DurationSecondType>;
pub type DurationMillisecondArray = PrimitiveArray<DurationMillisecondType>;
pub type DurationMicrosecondArray = PrimitiveArray<DurationMicrosecondType>;
pub type DurationNanosecondArray = PrimitiveArray<DurationNanosecondType>;
```
