Blob Storage — Rust SDK Quick Reference

Condensed from azure-storage-blob-rust. Full patterns (container ops, blob properties, RBAC permissions) in the azure-storage-blob-rust plugin skill if installed.

Install

cargo add azure_storage_blob azure_identity

Quick Start

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

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

Non-Obvious Patterns

use azure_core::http::RequestContent;
blob_client.upload(RequestContent::from(data.to_vec()), false, u64::try_from(data.len())?, None).await?;
