Insufficient documentation to get a basic get_flight_info() working

[adsharma]

Describe the bug

Python has this cookbook. C++ has one too. There are many blog posts on this topic.

But I couldn't find one for Rust.

To Reproduce

Run the steps in the README here:

https://github.com/adsharma/ashdb/tree/in_memory_kv

It's a toy kv store backed by a hashmap. I get:

./target/debug/flight_sql_client --host localhost --port 50051 db-schemas %
Error: read flight data

Caused by:
    0: collect data stream
    1: Decode error: Error decoding root message: Type `i32` at position 1818585414 is unaligned.

Expected behavior

Successful listing of schemas.
