Async is a composable asynchronous I/O framework for Ruby based on io-event and timers.
"Lately I've been looking into
async, as one of my projects – tus-ruby-server – would really benefit from non-blocking I/O. It's really beautifully designed." – janko
Features
- Scalable event-driven I/O for Ruby. Thousands of clients per process!
- Light weight fiber-based concurrency. No need for callbacks!
- Multi-thread/process containers for parallelism.
- Growing eco-system of event-driven components.
Usage
Please browse the source code index or refer to the guides below.
