## What it is
PhxRPC is a compact C++ RPC framework from Tencent's WeChat backend team, using Protobuf as IDL to generate client and server code. It features a half-sync/half-async epoll-based IO model with coroutine workers and built-in adaptive overload protection.

## Use cases
- build a lightweight C++ microservice with protobuf-defined RPC interfaces
- generate client and server stubs from proto files
- handle high-concurrency RPC calls with coroutine workers
- add adaptive overload protection to a C++ backend service
- implement backup request patterns for latency reduction

## When to choose
- you need a tiny, dependency-light C++ RPC framework (450K library)
- you want protobuf-based IDL code generation for C++ services
- you need high QPS on Linux with epoll and coroutine support

## When to avoid
- you need multi-process mode, which is unsupported
- you target Windows or non-Linux platforms
- you want a batteries-included service mesh with service discovery and tracing

## Facets
- artifact type: framework
- maturity: maintenance
- function: rpc, networking, concurrency, middleware
- domain: backend, microservices, developer-tools
- platform: cpp, cli
- tags: protobuf-idl, coroutine, epoll, overload-protection, wechat-team, half-sync-half-async, linux
