Expand description

Helper to convert to/from protobuf Any message to a specific FlightSQL command message.

§Example

let flightsql_message = CommandStatementQuery {
  query: "SELECT * FROM foo".to_string(),
  transaction_id: None,
};

// Given a packed FlightSQL Any message
let any_message = Any::pack(&flightsql_message).unwrap();

// decode it to Command:
match Command::try_from(any_message).unwrap() {
  Command::CommandStatementQuery(decoded) => {
   assert_eq!(flightsql_message, decoded);
  }
  _ => panic!("Unexpected decoded message"),
}
