What about `short`/`Int16`?

[StingyJack]

So many other int types here but not an int16

Hi @StingyJack, thank you for reaching out.

gRPC/Protobuf doesn't support 16-bits integer. For the list of supported scalar value types, please refer Scalar Value Types - Protobuf Language Guide (proto3) or Supported Scalar Value Types

To add to reply above, protobuf uses a variable length encoding for integers. Assuming your goal was to optimize the wire transmission, forcing a smaller width integer isn't needed.

This document describes the difference in type systems and offers suggestions for other primitive types but it does not cover short/int16.

Data lost from a narrowing conversion is the concern. I don't always have control over the existing model types. Best I can come up with is when the model property is a short and the incoming value is > short.MaxValue to throw an exception. Curious to hear about alternative approaches.

I was about to suggest something along those lines. @JamesNK anything to add?

Considering the original issue is answered and it's open for a very long, this can be closed now.

[StingyJack]

@erjain - This was opened to get the documentation updated to include the appropriate advice. Its not a support issue that can be resolved when a solution can be given.

[erjain]

Sure @StingyJack. Hi @JamesNK, any suggestions?
