rio

An async runtime based on liburing.

Warning

Doesn't use raw io_uring, I am using linux liburing abstraction layer/library. Single Threaded only.

Read requirments.

Building

$ g++ ./bld.cpp -o bld --std=c++23 && ./bld

You can find precompiled modules in ./bin/pcms/ & linking files/libs in ./bin/libs/

Follow instructions if bulding std module fails.

Requirements

• Clang 21.1
  • basically modules and c++23 support
• libc++
• liburing

Usage

Import rio module

import rio
// Implementation

Compile

clang++ -o main main.cpp -std=c++23 -stdlib=libc++ -fprebuilt-module-path=./bin/pcms/ -fprebuilt-module-path=./bin/std/ -L./bin/libs/ -lrio  -luring
clang++ ./examples/04-future-echo-server.cpp -o main2 -std=c++23 ./bin/libs/librio.a -fprebuilt-module-path=./bin/pcms -fprebuilt-module-path=./bin/std -luring

Notes

• If you are doing incremental builds and clang cries, try bld -build. This doesn't build std again.
• If you want to compile std again too, do bld -build-all, but it will compile whole thing again.
