Crate unitycatalog_common 

Shared types and utilities for the Unity Catalog server and client crates.

Most of the crate is the generated Unity Catalog data model, produced from the protobuf definitions in proto/ and re-exported from models. On top of that it collects the hand-written pieces both sides of the API depend on:

• error — the crate-wide Error and Result types.
• reference — the uc:// URL scheme for addressing catalog securables (UCReference).
• [store] — the storage-abstraction trait (ResourceStore) implemented by backends (feature store).
• [services] — envelope encryption for sealing sensitive fields inline (feature store).
• [credentials_ext] — conversions to the olai-storage-credentials / olai-credential-vending types (features storage-credentials, credential-vending).
• [metric_view] — the single parser for Unity Catalog metric-view definitions (feature metric-view).

Feature flags

The crate is feature-flag heavy so that downstream crates pull in only what they need. Each generated model package sits behind a resource feature named after its module (catalogs, tables, credentials, …); all-resources enables them all. rest-client and all-resources are on by default; grpc, axum, sqlx, store, metric-view, python, and node gate the corresponding integrations. store and python span every resource and imply all-resources. See the crate README for the full table.
