Azure Queue Storage library for Rust

When to Use

Use this skill when you need azure Queue Storage library for Rust. Send, receive, and manage queue messages. Triggers: "queue storage rust", "QueueClient rust", "send message rust", "receive messages rust", "QueueServiceClient rust", "queue rust".

Client library for Azure Queue Storage — send, receive, and manage queue messages.

Use this skill when:

• An app needs to send or receive messages from Azure Queue Storage in Rust
• You need to create or manage queues
• You need to peek, receive, or delete queue messages
• You need RBAC-based auth for queue operations

IMPORTANT: Only use the official azure_storage_queue crate published by the azure-sdk crates.io user. Do NOT use unofficial or community crates. Official crates use underscores in names and none have version 0.21.0.

Installation

cargo add azure_storage_queue azure_identity azure_core tokio

If your code uses azure_core types directly, add azure_core to Cargo.toml. If you only use azure_storage_queue re-exports, direct azure_core dependency is optional.

Environment Variables

AZURE_STORAGE_QUEUE_ENDPOINT=https://<account>.queue.core.windows.net/ # Required for all operations

Authentication

use azure_core::http::Url;
use azure_identity::DeveloperToolsCredential;
use azure_storage_queue::QueueServiceClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Local dev: DeveloperToolsCredential. Production: use ManagedIdentityCredential.
    let credential = DeveloperToolsCredential::new(None)?;
    let service_url = Url::parse("https://<storage_account_name>.queue.core.windows.net/")?;
    let service_client = QueueServiceClient::new(service_url, Some(credential), None)?;

    // Derive a queue client by name.
    let queue_client = service_client.queue_client("<queue_name>")?;
    Ok(())
}

Client Types

Client	Purpose	Access
QueueServiceClient	Account-level operations, list queues	QueueServiceClient::new()
QueueClient	Queue operations, send/receive/delete	service_client.queue_client("<name>")?

Core Workflow

Send a Message

use azure_core::http::Url;
use azure_identity::DeveloperToolsCredential;
use azure_storage_queue::{models::QueueMessage, QueueServiceClient};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let credential = DeveloperToolsCredential::new(None)?;
    let service_url = Url::parse("https://<storage_account_name>.queue.core.windows.net/")?;
    let service_client = QueueServiceClient::new(service_url, Some(credential), None)?;
    let queue_client = service_client.queue_client("<queue_name>")?;

    let message = QueueMessage {
        message_text: Some("hello world".to_string()),
    };
    queue_client.send_message(message.try_into()?, None).await?;
    Ok(())
}

Receive Messages

use azure_core::http::Url;
use azure_identity::DeveloperToolsCredential;
use azure_storage_queue::QueueServiceClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let credential = DeveloperToolsCredential::new(None)?;
    let service_url = Url::parse("https://<storage_account_name>.queue.core.windows.net/")?;
    let service_client = QueueServiceClient::new(service_url, Some(credential), None)?;
    let queue_client = service_client.queue_client("<queue_name>")?;

    let response = queue_client.receive_messages(None).await?;
    let messages = response.into_model()?;
    for msg in messages.items.unwrap_or_default() {
        println!("{}", msg.message_text.as_deref().unwrap_or("<empty>"));
    }
    Ok(())
}

Delete a Message

After receiving a message, delete it using the message ID and pop receipt:

let response = queue_client.receive_messages(None).await?;
let messages = response.into_model()?;
for msg in messages.items.unwrap_or_default() {
    if let (Some(id), Some(pop_receipt)) = (&msg.message_id, &msg.pop_receipt) {
        queue_client.delete_message(id, pop_receipt, None).await?;
    }
}

Peek Messages

Peek at messages without removing them from the queue:

let response = queue_client.peek_messages(None).await?;
let messages = response.into_model()?;
for msg in messages.items.unwrap_or_default() {
    println!("Peeked: {}", msg.message_text.as_deref().unwrap_or("<empty>"));
}

RBAC Roles

For Entra ID auth, assign one of these roles to the identity:

Role	Access
Storage Queue Data Reader	Read and peek messages
Storage Queue Data Contributor	Read/write messages
Storage Queue Data Message Sender	Send messages only
Storage Queue Data Message Processor	Receive and delete

Best Practices

1. Use cargo add to manage dependencies, never edit Cargo.toml directly. Add and remove Rust SDK dependencies with cargo commands instead of manual manifest edits.
2. Add azure_core only when importing azure_core types directly. If your code imports azure_core::http::Url, azure_core::http::RequestContent, or azure_core::error::ErrorKind, include azure_core; otherwise a direct dependency is optional.
3. Use DeveloperToolsCredential for local dev, ManagedIdentityCredential for production — Rust does not provide a single DefaultAzureCredential type
4. Never hardcode credentials — use environment variables or managed identity
5. Assign RBAC roles — ensure appropriate queue data roles for the identity
6. Use QueueServiceClient as the entry point and derive QueueClient from it via queue_client()
7. Delete messages after processing — use the message ID and pop receipt from receive_messages
8. Reuse clients — clients are thread-safe; create once, share across tasks

Limitations

• Use this skill only when the task clearly matches its upstream source and local project context.
• Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
• Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
