-Which transport actually applies the options:
-
-- `GuzzleTransport` maps them to Guzzle's `timeout` and `connect_timeout`, and sends with `http_errors` disabled. A cURL timeout (error 28) is thrown as `TransportTimeoutException`, which extends `TransportException`, so a timeout is distinguishable from a refused connection.
-- `Psr18Transport` ignores them. PSR-18 has no per-request options, so configure timeouts on the wrapped client instead.
+The bundled `Psr18Transport` ignores them. PSR-18 has no per-request options, so configure timeouts on the wrapped client instead. To honour per-request options, implement your own `Transport` and read them from the `TransportOptions` argument. Throw `TransportTimeoutException` (extends `TransportException`) on timeout so callers can tell a timeout from a refused connection.
