Inject and Extract with BINARY format

I have tried and cannot manage to get the Inject and extract with Binary work across 2 node on microservice. The communication between service is using rabitMQ.

Can anyone help guild me how to get it done?

Please correct me, if I'm wrong: For me it looks like there is no logic behind the inject/extract functions.

           // The default behavior is a no-op. 
        
           protected _inject(spanContext: SpanContext, format: string, carrier: any): void { 
        
           } 
        
           // The default behavior is to return a no-op SpanContext. 
        
           protected _extract(format: string, carrier: any): SpanContext | null { 
        
               return Noop.spanContext!; 
        
           }

I got a working way around with TEXT_MAP_FORMAT.

	// The default behavior is a no-op.
	protected _inject(spanContext: SpanContext, format: string, carrier: any): void {

	// The default behavior is to return a no-op SpanContext.
	protected _extract(format: string, carrier: any): SpanContext \| null {
	return Noop.spanContext!;
