# Azure Cosmos DB SDK for Rust


Client library for Azure Cosmos DB NoSQL API — globally distributed, multi-model database.


Installation


sh 
cargo add azure_data_cosmos azure_identity

Environment Variables


bash 
COSMOS_ENDPOINT=https://<account>.documents.azure.com:443/
COSMOS_DATABASE=mydb
COSMOS_CONTAINER=mycontainer

Authentication


rust 
use azure_identity::DeveloperToolsCredential;
use azure_data_cosmos::CosmosClient;

let credential = DeveloperToolsCredential::new(None)?;
let client = CosmosClient::new(
    "https://<account>.documents.azure.com:443/",
    credential.clone(),
    None,
)?;

Client Hierarchy


| Client | Purpose | Get From |

|--------|---------|----------|

| `CosmosClient` | Account-level operations | Direct instantiation |

| `DatabaseClient` | Database operations | `client.database_client()` |

| `ContainerClient` | Container/item operations | `database.container_client()` |


Core Workflow


Get Database and Container Clients


rust 
let database = client.database_client("myDatabase");
let container = database.container_client("myContainer");

Create Item


rust 
use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
struct Item {
    pub id: String,
    pub partition_key: String,
    pub value: String,
}

let item = Item {
    id: "1".into(),
    partition_key: "partition1".into(),
    value: "hello".into(),
};

container.create_item("partition1", item, None).await?;

Read Item


rust 
let response = container.read_item("partition1", "1", None).await?;
let item: Item = response.into_model()?;

Replace Item


rust 
let mut item: Item = container.read_item("partition1", "1", None).await?.into_model()?;
item.value = "updated".into();

container.replace_item("partition1", "1", item, None).await?;

Patch Item


rust 
use azure_data_cosmos::models::PatchDocument;

let patch = PatchDocument::default()
    .with_add("/newField", "newValue")?
    .with_remove("/oldField")?;

container.patch_item("partition1", "1", patch, None).await?;

Delete Item


rust 
container.delete_item("partition1", "1", None).await?;

Key Auth (Optional)


Enable key-based authentication with feature flag:


sh 
cargo add azure_data_cosmos --features key_auth

Best Practices


1. **Always specify partition key** — required for point reads and writes

2. **Use `into_model()?`** — to deserialize responses into your types

3. **Derive `Serialize` and `Deserialize`** — for all document types

4. **Use Entra ID auth** — prefer `DeveloperToolsCredential` over key auth

5. **Reuse client instances** — clients are thread-safe and reusable
