@spec from_erlavro(
  term(),
  keyword()
) :: {:ok, Avrora.Schema.t()} | {:error, term()}

Convert erlavro format to the Schema struct.

Examples

iex> payload =
...>   {:avro_record_type, "Payment", "io.acme", "", [],
...>        [
...>          {:avro_record_field, "id", "", {:avro_primitive_type, "string", []}, :undefined,
...>           :ascending, []},
...>          {:avro_record_field, "amount", "", {:avro_primitive_type, "double", []}, :undefined,
...>           :ascending, []}
...>        ], "io.acme.Payment", []}
iex> {:ok, schema} = Avrora.Schema.Encoder.from_erlavro(payload)
iex> schema.id
nil
iex> schema.full_name
"io.acme.Payment"copy

@spec from_json(String.t(), reference_lookup_fun()) ::
  {:ok, Avrora.Schema.t()} | {:error, term()}

Parse Avro schema JSON and convert to the Schema struct.

Examples

iex> json = ~s({"namespace":"io.acme","type":"record","name":"Payment","fields":[{"name":"id","type":"string"},{"name":"amount","type":"double"}]})
iex> {:ok, schema} = Avrora.Schema.Encoder.from_json(json)
iex> schema.full_name
"io.acme.Payment"copy

@spec reference_lookup(String.t()) :: {:ok, String.t()} | {:error, term()}

An example of a reference lookup which returns empty JSON body

@spec to_erlavro(Avrora.Schema.t()) :: {:ok, term()} | {:error, term()}

Convert struct to erlavro format and look it up in avro_schema_store.

Examples

iex> json = ~s({"namespace":"io.acme","type":"record","name":"Payment","fields":[{"name":"id","type":"string"},{"name":"amount","type":"double"}]})
iex> {:ok, schema} = Avrora.Schema.Encoder.from_json(json)
iex> {:ok, {type, _, _, _, _, _, full_name, _}} = Avrora.Schema.Encoder.to_erlavro(schema)
iex> full_name
"io.acme.Payment"
iex> type
