Fetcher<Key, T> class
base
Fetcher is used by Stock to fetch network records of the type T
for a given key of the type Key. The return type is Stream to
allow for multiple results per request.
Note: Stock does not catch exceptions thrown by a Fetcher. Use StockResponseError to communicate expected errors.
See ofFuture for easily translating from a regular Future function.
See ofStream, for easily translating to StockResponse (and
automatically transforming exceptions into StockResponseError).
