@spec collect(term()) :: {:ok, [String.t()]} | {:error, term()}

Collect non local type referenced types from erlavro structure.

Type definition aliases counted as type definitions too.

Every json-string type value considered to be a reference if it's not one of the reserved by Avro Specification types, such as:

• int - null - enum
• long - boolean - array
• float - string - map
• double - record - union
• bytes - fixed

Examples

iex> json_schema = File.read!("test/fixtures/schemas/io/confluent/Account.avsc")
iex> erlavro = :avro_json_decoder.decode_schema(json_schema, allow_bad_references: true)
iex> Avrora.Schema.ReferenceCollector.collect(erlavro)
{:ok, ["io.confluent.Email", "io.confluent.Messenger", "io.confluent.PaymentHistory"]}
