> Key: AVRO-3683
> URL: https://issues.apache.org/jira/browse/AVRO-3683
> Project: Apache Avro
> Issue Type: Bug
> Components: rust
> Affects Versions: 1.11.1
> Reporter: Mark Farnan
> Priority: Major
> Labels: pull-request-available
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Avro permits Schema definitions to reference Types defined in other Schema
> files.
> Currently these can be parsed with Schema:parse_list, but the output of this
> can't be used in Writer, Reader, (or to_avro_datum, from_avro_datum)
> * These functions only take a single 'schema' and can't resolve the
> References
> * Schema:parse_list puts in 'refs' for the external dependencies, but
> doesn't seem to populate the UnionSchema's, so they can be resolved.
>
> +Example of dependant schemas:+
> letschema_TypeA=r#"
> {
> "type": "record",
> "namespace": "base.name.space",
> "name": "MultiSchemaTestTypeA",
> "fields":
> [
> { "name": "b", "type": ["null", "some.name.space.MultiSchemaTestTypeB"] }
> ,
> { "name": "c", "type": \\{ "type": "map", "values":
> "some.name.space.MultiSchemaTestTypeB" }
> , "default": {}
> }
> ]
