Trait MessageBusBacking 

pub trait MessageBusBacking {
    // Required methods
    fn is_closed(&self) -> bool;
    fn publish(&self, message: BusMessage);
    fn close(&mut self);

    // Provided method
    fn take_receiver(&mut self) -> Result<MessageBusExternalReceiver> { ... }
}

External message bus backing facade.

Implementations own the concrete backing technology and provide the runtime-facing publication surface used by the core bus. With the live feature, the same backing can also hand an inbound receiver to the live bridge.

Required Methods

fn is_closed(&self) -> bool

Returns true if the backing has been closed.

fn publish(&self, message: BusMessage)

Queues a serialized bus message for external egress.

fn close(&mut self)

Closes the backing and releases any owned resources.

Provided Methods

fn take_receiver(&mut self) -> Result<MessageBusExternalReceiver>

Takes the inbound message receiver for live bridge consumption.

Errors

Returns an error if the receiver has already been taken or is unavailable.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
