Azure Blob Storage SDK for Rust
Client library for Azure Blob Storage — Microsoft's object storage solution for the cloud.
Installation
cargo add azure_storage_blob azure_identity
Environment Variables
AZURE_STORAGE_ACCOUNT_NAME=<storage-account-name>
# Endpoint: https://<account>.blob.core.windows.net/
Authentication
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),
Some(BlobClientOptions::default()),
)?;
Client Types
| Client | Purpose |
|--------|---------|
| BlobServiceClient | Account-level operations, list containers |
| BlobContainerClient | Container operations, list blobs |
| BlobClient | Individual blob operations |
Core Operations
Upload Blob
use azure_core::http::RequestContent;
let data = b"hello world";
blob_client
.upload(
RequestContent::from(data.to_vec()),
false, // overwrite
u64::try_from(data.len())?,
None,
)
.await?;
Download Blob
let response = blob_client.download(None).await?;
let content = response.into_body().collect_bytes().await?;
println!("Content: {:?}", content);
Get Blob Properties
let properties = blob_client.get_properties(None).await?;
println!("Content-Length: {:?}", properties.content_length);
Delete Blob
blob_client.delete(None).await?;
Container Operations
use azure_storage_blob::BlobContainerClient;
let container_client = BlobContainerClient::new(
"https://<account>.blob.core.windows.net/",
"container-name",
Some(credential),
None,
)?;
// Create container
container_client.create(None).await?;
// List blobs
let mut pager = container_client.list_blobs(None)?;
while let Some(blob) = pager.try_next().await? {
println!("Blob: {}", blob.name);
}
Best Practices
- Use Entra ID auth —
DeveloperToolsCredentialfor dev,ManagedIdentityCredentialfor production - Specify content length — required for uploads
- Use
RequestContent::from()— to wrap upload data - Handle async operations — use
tokioruntime - Check RBAC permissions — ensure "Storage Blob Data Contributor" role
RBAC Permissions
For Entra ID auth, assign one of these roles:
Storage Blob Data Reader— read-onlyStorage Blob Data Contributor— read/writeStorage Blob Data Owner— full access including RBAC

KQL language expertise for writing correct, efficient Kusto Query Language queries. Covers syntax gotchas, join patterns, dynamic types, datetime pitfalls, regex patterns, serialization, memory management, result-size discipline, and advanced functions (geo, vector, graph). USE THIS SKILL whenever writing, debugging, or reviewing KQL queries — even simple ones — because the gotchas section prevents the most common errors that waste tool calls and cause expensive retry cascades. Trigger on: KQL, Kusto, ADX, Azure Data Explorer, Fabric Real-Time Intelligence, EventHouse, Log Analytics, log analysis, data exploration, time series, anomaly detection, summarize, where clause, join, extend, project, let statement, parse operator, extract function, any mention of pipe-forward query syntax.
