Nuclei

Nuclei is a proactive IO system which is runtime agnostic and can work with any runtime. Proactive system's design principles matching to Boost Asio. Nuclei is not using conventional reactor approach. It is completely asynchronous, and it's wrapping poll based IO proactive fashion.

Nuclei uses epoll on Linux as primary evented IO backend, secondarily (if your system supports) you can use io_uring. On MacOS, Nuclei is using kqueue. On Windows, IOCP backend is used.

Current io_uring implementation needs Linux kernel 5.6+.

Features

• Async TCP, UDP, Unix domain sockets and files...
• Proactor system don't block.
• Scatter/Gather operations
• Minimal allocation as much as possible.
• More expressive than any other runtime.
• Completely asynchronous I/O system with lock free programming.

Examples

Executor

Executor is by default set to Bastion's executor. If you want to use different executor, you can use one of the available runtimes with one of these features: bastion, asyncstd, tokio, smol.
