What this skill does
Azure Cosmos DB SDK for Rust Client library for Azure Cosmos DB NoSQL API — globally distributed, multi-model database. Installation Environment Variables Authentication Client Hierarchy Client Purpose Get From -------- --------- ---------- CosmosClient Account-level operations Direct instantiation DatabaseClient Database operations client.databaseclient() ContainerClient Container/item operations database.containerclient() Core Workflow Get Database and Container Clients Create Item Read Item Replace Item Patch Item Delete Item Key Auth (Optional) Enable key-based authentication with feature flag: Best Practices 1. Always specify partition key — required for point reads and writes 2. Use intomodel()? — 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 Reference Links Resource Link ---------- ------ API Reference https://docs.rs/azuredatacosmos Source Code https://github.com/Azure/azure-sdk-for-rust/tree/main/sdk/cosmos/azuredatacosmos crates.io https://crates.io/crates/azuredatacosmos When to Use This skill is applicable to execute the workflow or actions described in the overview.
