messaging.system\n * - messaging.operation\n * - messaging.destination.name\n *\n * **Use Cases:**\n * - Publishing messages to queues/topics\n * - Consuming messages from queues/topics\n * - Event-driven architectures\n *\n * @param config - Messaging operation configuration\n * @returns Traced function factory with Messaging attributes\n *\n * @example Publishing to Kafka\n * ```typescript\n * import { traceMessaging } from 'autotel/semantic-helpers'\n * import { kafka } from './kafka'\n *\n * const producer = kafka.producer()\n *\n * export const publishEvent = traceMessaging({\n *   system: 'kafka',\n *   operation: 'publish',\n *   destination: 'user-events'\n * })(ctx => async (event: { type: string; userId: string; data: object }) => {\n *   ctx.setAttribute('messaging.message.type', event.type)\n *   ctx.setAttribute('messaging.kafka.partition', 0)\n *\n *   await producer.send({\n *     topic: 'user-events',\n *     messages: [\n *       {\n *         key: event.userId,\n *         value: JSON.stringify(event.data)\n *       }\n *     ]\n *   })\n *\n *   ctx.setAttribute('messaging.message.id', event.userId)\n * })\n * ```\n *\n * @example Consuming from RabbitMQ\n * ```typescript\n * import { traceMessaging } from 'autotel/semantic-helpers'\n * import { channel } from './rabbitmq'\n *\n * export const processOrder = traceMessaging({\n *   system: 'rabbitmq',\n *   operation: 'process',\n *   destination: 'orders'\n * })(ctx => async (message: { orderId: string; items: object[] }) => {\n *   ctx.setAttribute('messaging.message.id', message.orderId)\n *   ctx.setAttribute('messaging.message.body.size', JSON.stringify(message).length)\n *\n *   // Process order logic\n *   const result = await processOrderInternal(message)\n *\n *   ctx.setAttribute('messaging.operation.result', 'success')\n *   return result\n * })\n * ```\n *\n * @example AWS SQS with batch processing\n * ```typescript\n * import { traceMessaging } from 'autotel/semantic-helpers'\n * import { SQS } from '@aws-sdk/client-sqs'\n *\n * const sqs = new SQS()\n *\n * export const sendBatch = traceMessaging({\n *   system: 'aws_sqs',\n *   operation: 'publish',\n *   destination: 'notifications-queue'\n * })(ctx => async (messages: Array<{ id: string; body: object }>) => {\n *   ctx.setAttribute('messaging.batch.message_count', messages.length)\n *\n *   const result = await sqs.sendMessageBatch({\n *     QueueUrl: process.env.QUEUE_URL,\n *     Entries: messages.map(msg => ({\n *       Id: msg.id,\n *       MessageBody: JSON.stringify(msg.body)\n *     }))\n *   })\n *\n *   ctx.setAttribute('messaging.operation.success_count', result.Successful?.length || 0)\n *   ctx.setAttribute('messaging.operation.failed_count', result.Failed?.length || 0)\n *\n *   return result\n * })\n * ```\n *\n * @public\n */\nexport function traceMessaging<TArgs extends unknown[], TReturn>(\n  config: MessagingConfig,\n) {\n  return (\n    fnFactory: (ctx: TraceContext) => (...args: TArgs) => Promise<TReturn>,\n  ): ((...args: TArgs) => Promise<TReturn>) => {\n    return trace<TArgs, TReturn>((ctx) => {\n      // Set semantic convention attributes\n      ctx.setAttribute('messaging.system', config.system);\n      if (config.operation) {\n        ctx.setAttribute('messaging.operation', config.operation);\n      }\n      if (config.destination) {\n        ctx.setAttribute('messaging.destination.name', config.destination);\n      }\n      if (config.attributes) {\n        for (const [key, value] of Object.entries(config.attributes)) {\n          if (value !== undefined && value !== null) {\n            // setAttribute only accepts primitives (string | number | boolean)\n            // Arrays and objects should be serialized\n            const attrValue =\n              typeof value === 'string' ||\n              typeof value === 'number' ||\n              typeof value === 'boolean'\n                ? value\n                : JSON.stringify(value);\n            ctx.setAttribute(key, attrValue);\n          }\n        }\n      }\n\n      // Call the user's factory to get their function and return it\n      return fnFactory(ctx);\n    });\n  };\n}\n"]}
