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

7## Install
8cargo add azure_storage_blob azure_identity
9 
10## Quick Start
11```rust
12use azure_identity::DeveloperToolsCredential;
13use azure_storage_blob::BlobClient;
14let credential = DeveloperToolsCredential::new(None)?;
15let blob_client = BlobClient::new("https://<account>.blob.core.windows.net/", "container", "blob", Some(credential), None)?;
16```
17 
18## Best Practices
19- Use Entra ID auth — `DeveloperToolsCredential` for dev, `ManagedIdentityCredential` for production
20- Specify content length — required for uploads
21- Use `RequestContent::from()` to wrap upload data
22- Handle async operations — use `tokio` runtime
23- Check RBAC permissions — ensure "Storage Blob Data Contributor" role
24 
25## Non-Obvious Patterns
26```rust
27use azure_core::http::RequestContent;
28blob_client.upload(RequestContent::from(data.to_vec()), false, u64::try_from(data.len())?, None).await?;
29```
