Expand description

Bundle of trait bounds an Rmw backend must satisfy to be exposed through RustBackendAdapter. Implemented automatically for any R: Rmw whose handle types use TransportError and are 'static.

Required Associated Types§

type Session: Session<Error = TransportError, PublisherHandle = Self::Publisher, SubscriptionHandle = Self::Subscription, ServiceHandle = Self::Service, ClientHandle = Self::Client> + 'static

type Client: ClientTrait<Error = TransportError> + 'static

Required Methods§

fn factory() -> Self

Construct a fresh factory instance. Called inside the open trampoline. Equivalent to R::default() for backends that derive(Default); the indirection keeps the door open for future per-backend registration knobs.
