Libuv is a cross platform asynchronous IO implementation that powers NodeJS. It supports sockets, both UDP and TCP, filesystem operations, TTY, Pipes and other asynchronous primitives like timer, check, prepare and idle.

UV.rb is FFI Ruby bindings for libuv.

Usage¶ ↑

Create a uv loop or use a default one

require 'uv'

loop = UV::Loop.default
# or
# loop = UV::Loop.new

timer = loop.timer
timer.start(50000, 0) do |error|
  p error if error
  puts "50 seconds passed"
  timer.close
end

loop.run
