Azure Cosmos DB SDK for Rust

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

Installation

cargo add azure_data_cosmos azure_identity

Environment Variables

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

Authentication

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

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

Create Item

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
  {
     id: ,
     partition_key: ,
     value: ,
}

  = Item {
    id: .(),
    partition_key: .(),
    value: .(),
};

container.(, item, ).?;
