Module resolution 

Control-plane schema capabilities and resolution policy. Shared schema-resolution policy. Discovery never consumes records or creates a target.

Structs

NativeSchema

One immutable native schema, including the semantics Arrow cannot express.

NativeSchemaArtifact

A transitive native definition and its scoped identity.

SchemaBinding

Immutable connector binding for one catalog generation.

SchemaCapabilities

A factory must declare its direction’s schema behavior in its connector metadata.

SchemaFieldMapping

Declarative mapping compiled once by the connector when it activates.

Enums

SchemaDirection

Direction in which a connector applies its schema contract.

SchemaDiscovery

Available source of schema authority, independently of transport support.

SchemaOrigin

Authority that established the immutable logical schema.

SchemaPreparation

External preparation is independent of metadata discovery.

Functions

bind_external

Attach an external schema under the default exact-name/type policy.

binding_error

Preserve the existing connector schema-error taxonomy.

fixed_binding

Bind a fixed protocol whose decoder emits the complete declared field list.

logical_binding

Create a validated logical-only reader or writer binding.

project_batch

Apply a prepared exact-name mapping without casts or per-row conversion.

validate_prepared_writer

Validate that authorized external preparation retains the resolved query contract. Native identity, writer metadata and mappings may be finalized by the preparation hook.
