Microlib for socket RPC
Project description
socket_rpc
socket_rpc
is a very simple microlib for remote procedure calls (RPC) over sockets in Python.
It exposes two class:
RPCServer
- acts as a server for a Python RPCRPCClient
- allows you to call a function, registered on another host with therpc
decorator.
Install with:
pip install socket_rpc
It has no external dependencies and is less than 100 lines of code.
It doesn't fork the process and guarantees you that the calls to a server will be processed in the same order in which they were done.
Quick server example
To expose a function over TCP, just decorate it with the rpc
decorator:
import logging
import sys
import numpy as np
from socket_rpc import RPCServer
logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)
def callback0(np_arr: np.ndarray):
print('0', np_arr.shape)
def callback1(np_arr: np.ndarray):
print('1', np_arr.shape)
server = RPCServer(host='localhost', port=61000, buffer_size=1 * 1024 * 1024)
server.add_fn(callback0)
server.add_fn(callback1)
server.serve()
Quick call example
To call a function already exposed with the rpc
decorator, just use the rpc_call
function:
import numpy as np
from socket_rpc import RPCClient
client = RPCClient('127.0.0.1', 5555)
client.callback0(np.arange(100))
client.callback1(np.arange(10))
