Manipulate [Protocol Buffers](https://developers.google.com/protocol-buffers/) schemas and records in a generic manner without compiled classes, similar to [Avro](https://avro.apache.org/)'s `GenericRecord`.

# Usage

```scala

import me.lyh.protobuf.generic._

val schema1 = Schema.of[MyRecord]  // generic representation of the protobuf schema

val jsonString = schema1.toJson  // serialize to JSON

val schema2 = Schema.fromJson(jsonString)  // deserialize from JSON

// read protobuf binary without original class

val bytes1: Array[Byte] = // binary MyRecord

val reader = GenericReader.of(schema2)

val record1 = reader.read(bytes1)  // generic record, i.e. Map[String, Any]

val jsonRecord = record1.toJson  // JSON string

// write protobuf binary without orignal class

val record2 = GenericRecord.fromJson(jsonRecord)  // generic record, i.e. Map[String, Any]

val writer = GenericWriter.of(schema2)

val bytes2 = writer.write(record2)  // binary MyRecord

```
