Azure Blob Storage SDK for Rust Acceptance Criteria

Crate: azure_storage_blobRepository: https://github.com/Azure/azure-sdk-for-rust/tree/main/sdk/storage/azure_storage_blobPurpose: Skill testing acceptance criteria for validating generated Rust code correctness

---

0. Dependency Management Gate (Required)

0.1 ✅ CORRECT: Use cargo commands for dependency changes

cargo add azure_storage_blob azure_identity tokio
cargo add azure_core
cargo remove azure_core

0.2 ✅ CORRECT: Add azure_core only for direct azure_core imports

use azure_core::http::Url;
use azure_storage_blob::BlobServiceClient;
// Direct azure_core import is used, so `azure_core` should be a direct dependency.

0.3 ❌ INCORRECT: Manual Cargo.toml dependency edits in generated guidance

# WRONG in generated guidance - use `cargo add` / `cargo remove` commands instead
[dependencies]
azure_core = "*"

0.4 ❌ INCORRECT: Requiring azure_core when no direct azure_core imports exist

use azure_storage_blob::BlobServiceClient;
// No direct azure_core import here, so forcing direct azure_core dependency is unnecessary.

---

1. Correct Import Patterns

1.1 ✅ CORRECT: Client Imports

use azure_storage_blob::{BlobClient, BlobClientOptions};
use azure_storage_blob::BlobContainerClient;
use azure_storage_blob::BlobServiceClient;
use azure_core::http::RequestContent;
use azure_identity::DeveloperToolsCredential;

---

2. Client Creation

2.1 ✅ CORRECT: BlobClient with Entra ID

use azure_identity::DeveloperToolsCredential;
use azure_storage_blob::{BlobClient, BlobClientOptions};

let credential = DeveloperToolsCredential::new(None)?;
let blob_client = BlobClient::new(
    "https://<account>.blob.core.windows.net/",
    "container-name",
    "blob-name",
    Some(credential),
    None,
)?;

2.2 Anti-Patterns (ERRORS)

❌ INCORRECT: Hardcoded account key

// WRONG - use Entra ID authentication
let account_key = "actual-key-here";

---

3. Blob Operations

3.1 ✅ CORRECT: Upload Blob

use azure_core::http::RequestContent;

let data = b"hello world";
blob_client
    .upload(RequestContent::from(data.to_vec()), None)
    .await?;

3.2 ✅ CORRECT: Download Blob

let response = blob_client.download(None).await?;
let content = response.into_body().collect_bytes().await?;

3.3 ✅ CORRECT: Get Blob Properties

let properties = blob_client.get_properties(None).await?;

3.4 ✅ CORRECT: Delete Blob

blob_client.delete(None).await?;

3.5 Anti-Patterns (ERRORS)

---

4. Container Operations

4.1 ✅ CORRECT: Create Container Client

use azure_storage_blob::BlobContainerClient;

let container_client = BlobContainerClient::new(
    "https://<account>.blob.core.windows.net/",
    "container-name",
    Some(credential),
    None,
)?;

4.2 ✅ CORRECT: Create Container

container_client.create(None).await?;

---

5. Best Practices

5.1 ✅ CORRECT: Use RequestContent for upload data

use azure_core::http::RequestContent;

let data = RequestContent::from(bytes.to_vec());

5.2 ✅ CORRECT: Specify content length

blob_client.upload(data, None).await?;
