FutureProof

FutureProof provides concurrency extensions for Ruby.

Installation

Add this line to your application's Gemfile:

gem 'future_proof'

And then execute:

$ bundle

Or install it yourself as:

$ gem install future_proof

Usage

Future

future = FutureProof::Future.new { |a, b| a + b }

future.call(1, 2) # => executes in a thread

future.value # => returns value when ready

ThreadPool

thread_pool = FutureProof::ThreadPool.new(5)

10.times do |i|
  thread_pool.submit i, i + 1 do |a, b|
    a + b
  end
end

thread_pool.perform # executes 10 procs in 5 threads

thread_pool.values # releases threads and returns values

Exceptions

If exception happens inside a thread it doesn't affect the whole process. Exception is raised when accessing specific value:

thread_pool.values[3] # => raises exception
