'''
Extremely minimal streaming codec for a subset of protobuf. Supports uint32,
bytes, string, embedded message and repeated fields.
For de-sererializing (loading) protobuf types, object with `AsyncReader`
interface is required:
class AsyncReader:
async def areadinto(self, buffer):
"""
Reads `len(buffer)` bytes into `buffer`, or raises `EOFError`.
"""
For serializing (dumping) protobuf types, object with `AsyncWriter` interface is
required:
class AsyncWriter:
async def awrite(self, buffer):
"""
Writes all bytes from `buffer`, or raises `EOFError`.
