## What it is
rest_rpc is a modern C++20, header-only, high-performance RPC framework built on standalone asio and coroutines. It makes TCP-based remote procedure calls simple enough that users only need to focus on business logic.

## Use cases
- build rpc services in c++
- call remote functions over tcp from c++
- implement client-server communication with coroutines
- serialize and exchange structs between c++ services
- replace hand-written socket code with a simple rpc library

## When to choose
- you need an easy-to-use, header-only C++20 rpc framework
- you want coroutine-based async networking without writing socket code
- you need cross-platform high-performance tcp rpc in C++

## When to avoid
- you need cross-language rpc like gRPC
- your compiler does not fully support C++20 (gcc12+, clang15+, msvc2022 required)
- you need HTTP/REST APIs rather than binary rpc over TCP

## Facets
- artifact type: library
- maturity: active
- function: rpc, http-server, serialization, networking
- domain: developer-tools, microservices, backend, apis
- platform: windows, cpp, cross-platform
- tags: header-only, cpp20-coroutines, asio, tcp, high-performance, linux, macos
