Module export 

Available on crate feature contract only.

Machine-readable contract exports: JSON Schema and an OpenLineage SchemaDatasetFacet. Pure functions over a ContractSpec — no I/O. Used by faucet contract --export …; available to library callers too.

Constants

OPENLINEAGE_SCHEMA_FACET_URL

Pinned OpenLineage SchemaDatasetFacet schema URL used by to_openlineage_facet.

Functions

to_json_schema

Render the contract as a standalone JSON Schema (draft 2020-12) document.

to_openlineage_facet

Render the contract as an OpenLineage SchemaDatasetFacet — the same facet shape faucet-lineage attaches to dataset events, so downstream OpenLineage consumers can ingest the contract as a schema promise.
