No iterator for contract_details

[BigKahunaCanuck]

I would like to get the primary exchange for a stock symbol. This would allow me to cut down on the amount of data retrieved (only one exchange versus all available exchanges) for market data requests.

You can use contract_details to determine the primary exchange. From the ContractDetails struct your can find the primary exchange as follows.

contract_details.contract.primary_exchange

After you've done this once you can set the primary exchange when requesting contracts details to only receive data for that exchange.

let mut contract = Contract::stock("AAPL");   // this defaults exchange to SMART
contract.exchange = "NYSE";
client.contract_details(&contract);
