[GitHub] [arrow-rs] viirya opened a new issue, #1870: Add Decimal128 API and use it in DecimalArray and DecimalBuilder

viirya opened a new issue, #1870:
URL: https://github.com/apache/arrow-rs/issues/1870

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   Part of #131.
   
   Currently we directly use i128 in decimal related APIs, for example DecimalArray and DecimalBuilder APIs. However, in order to support 256-bit decimal, we need more consistent Decimal API. For example, in C++ Arrow, there are Decimal128 and Decimal256 classes.
   
   This proposes to have Decimal128 API and use it in DecimalArray and DecimalBuilder.
   
   **Describe the solution you'd like**
   
   Add Decimal128 API and use it in DecimalArray and DecimalBuilder.
   
   **Describe alternatives you've considered**
   Keep i128 in DecimalArray and DecimalBuilder. But there will be inconsistency between Decimal256 related APIs and also inconsistency between C++ Arrow and Rust Arrow APIs.
   
   **Additional context**
   Add any other context or screenshots about the feature request here.
