Struct OptionalTransport

pub struct OptionalTransport<T>(/* private fields */);
Expand description

Transport that is possibly disabled.

An OptionalTransport<T> is a wrapper around an Option<T>. If it is disabled (read: contains None), then any attempt to dial or listen will return MultiaddrNotSupported. If it is enabled (read: contains Some), then dialing and listening will be handled by the inner transport.
