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
