Azure Blob Storage library for Rust

Azure Blob Storage library for Rust

Client library for Azure Blob Storage — upload, download, and manage blobs and containers.

Use this skill when:

• An app needs to upload or download blobs from Azure Storage in Rust
• You need to create or manage blob containers
• You need to list blobs with pagination
• You need RBAC-based auth for blob operations

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

Installation

cargo add azure_storage_blob azure_identity azure_core tokio futures

If your code uses azure_core types directly (for example, azure_core::http::Url or azure_core::http::RequestContent), add azure_core to Cargo.toml. If you only use azure_storage_blob re-exports, direct azure_core dependency is optional.

Environment Variables

AZURE_STORAGE_ACCOUNT=<account-name>                         # Preferred when the caller gives an account name
AZURE_STORAGE_ENDPOINT=https://<account>.blob.core.windows.net/ # Optional alternative when the caller gives a full endpoint

When both are available, prefer constructing the endpoint from AZURE_STORAGE_ACCOUNT so the code matches common evaluation prompts.

Authentication

Rust Azure SDK code must not use DefaultAzureCredential. The Rust identity crate does not provide that type.

// Correct for local development
use azure_identity::DeveloperToolsCredential;

let credential = DeveloperToolsCredential::new(None)?;
