Azure Cosmos DB library for Rust

Client library for Azure Cosmos DB NoSQL API — document CRUD, containers, and globally distributed data.

Use this skill when:

• An app needs to store or query documents in Cosmos DB from Rust
• You need CRUD operations on items with partition keys
• You need key-based auth as an alternative to Entra ID

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

Installation

cargo add azure_data_cosmos azure_identity tokio

Do not add azure_core directly to Cargo.toml. It is re-exported by azure_data_cosmos.
