# Azure Event Hubs SDK for Rust Client library for Azure Event Hubs — big data streaming platform and event ingestion service. ## Installation ```sh cargo add azure_messaging_eventhubs azure_identity ``` ## Environment Variables ```bash EVENTHUBS_HOST=<namespace>.servicebus.windows.net EVENTHUB_NAME=<eventhub-name> ``` ## Key Concepts - **Namespace** — container for Event Hubs - **Event Hub** — stream of events partitioned for parallel processing - **Partition** — ordered sequence of events - **Producer** — sends events to Event Hub - **Consumer** — receives events from partitions ## Producer Client ### Create Producer ```rust use azure_identity::DeveloperToolsCredential; use azure_messaging_eventhubs::ProducerClient; let credential = DeveloperToolsCredential::new(None)?; let producer = ProducerClient::builder() .open("<namespace>.servicebus.windows.net", "eventhub-name", credential.clone()) .await?; ``` ### Send Single Event ```rust producer.send_event(vec![1, 2, 3, 4], None).await?; ``` ### Send Batch ```rust let batch = producer.create_batch(None).await?; batch.try_add_event_data(b"event 1".to_vec(), None)?; batch.try_add_event_data(b"event 2".to_vec(), None)?; producer.send_batch(batch, None).await?; ``` ## Consumer Client ### Create Consumer ```rust use azure_messaging_eventhubs::ConsumerClient; let credential = DeveloperToolsCredential::new(None)?; let consumer = ConsumerClient::builder() .open("<namespace>.servicebus.windows.net", "event...
