A modern, modular C++17 utility library focused on performance, portability and developer ergonomics.

Quick, practical building blocks for networking, crypto, IO, algorithms and system utilities — designed for production systems and developer productivity.

Highlights

• Lightweight, header-first-friendly APIs where appropriate.
• Battery-included tooling: tests, benchmarks and CI-friendly CMake setup.
• Portable to Linux/macOS/Windows using vcpkg and CMake.
• Focus on safety (RAII), clear error handling (std::error_code) and test coverage.

Quick start

1. Install vcpkg and required toolchain. See vcpkg.json for dependencies.

Windows (PowerShell):

# from project root
cmake -S . -B build -G "Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE="$env:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" -DBUILD_TEST=ON -DBUILD_BENCH=ON
cmake --build build --config Debug
cmake --build build --target tests --config Debug

macOS / Linux:

cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake -DBUILD_TEST=ON -DBUILD_BENCH=ON
cmake --build build
ctest --test-dir build

Modules (selected)

• algo — data structures & algorithms (skiplist, bloom filters, behavior trees)
• crypto — AES/DES/RSA/MD5/SHA, base64 utilities
• io — file/buffer utilities and async helpers
• net — TCP/UDP/HTTP/ZeroMQ helpers
• os — platform compatibility, process, env, signal
• sync — concurrency primitives and coroutine helpers
• testing — testing helpers and crash/debug utilities
• more detailed module docs: docs/modules.md and docs/modules_zh.md
