TMVar for Ractor inspired by Haskell's TMVar based on Ractor::TVar.
Add this line to your application's Gemfile:
gem 'ractor-tmvar'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install ractor-tmvar
require 'ractor/tmvar'
tv1 = Ractor::TMVar.new(0)
tv2 = Ractor::TMVar.new(0)
rs = 100.times.map do
Ractor.new tv1, tv2 do |v1, v2|
value1 = nil
value2 = nil
Ractor.atomically do
# take value like takeTMVar in Haskell
value1 = v1.take
value2 = v2.take
end
Ractor.atomically do
# set value like putTMVar in Haskell
v2.put(value2 + 2)
v1.put(value1 + 1)
end
end
end
rs.each(&:take)
tv1.read #=> 100
tv2.read #=> 200
