Required methods

fn claim() -> Option<(Requester<Self>, Responder<Self>)>[src]

This is the constructor for a (Requester, Responder) pair.

Returns singleton static instances until all that were allocated are used up, thereafter, None is returned.

unsafe fn reset_claims()[src]

Method purely for testing - do not use in production

Rationale: In production, interchanges are supposed to be set up as global singletons during intialization. In testing however, multiple test cases are run serially; without this reset, such tests would need to allocate an extremely large amount of clients.

It does not work to put this behind a feature flag, as macro expansion happens at call site and can't see the feature.
