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 — DeveloperToolsCredential for dev, ManagedIdentityCredential for production
Specify content length — required for uploads
Use RequestContent::from() — to wrap upload data
Handle async operations — use tokio runtime
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-only
Storage Blob Data Contributor — read/write
Storage Blob Data Owner — full access including RBAC

Anxiety-aware, evidence-driven collaboration for stalled or high-stakes work when a user says uncertainty, repeated setbacks, or lack of visible progress is causing significant anxiety or distress. Use immediately when explicitly invoked; when this fit is only inferred from the user's own account, ask permission before applying it. Preserve the user's ideal and turn grounded perspective-taking into persistent, bounded problem solving. Do not use to diagnose, provide therapy, manufacture certainty, or lower goals for reassurance.
