Performer

gem install performer

Performer is a tiny gem for scheduling blocks in a background thread, and optionally waiting for the return value.

Usage

performer = Performer.new

result = performer.sync { 2 + 1 }
result # => 3

future = performer.async { 2 + 1 }
future.value # => 3

future = performer.shutdown do
  puts "Performer has been properly shutdown."
end

future.value # wait for shutdown
