How do I pass processor_pool to the method inside the module?
class Dummy
def initialize
processor_pool = Concurrent::FixedThreadPool.new(10)
@threadpool = Module.new do
extend Concurrent::Promises::FactoryMethods
def self.default_executor
return processor_pool # this cannot find the processor_pool variable
end
end
end
end
I get the same error even if I make it an instance variable like @processor_pool
Something like this (I simplified your class a bit to get rid of dependencies for the sake of example, but its structure is the same):
class Dummy
attr_reader :threadpool
def initialize
processor_pool = "It works"
@threadpool = Module.new do
define_method :default_executor do
return processor_pool # this cannot find the processor_pool variable
end
module_function :default_executor
end
end
end
Dummy.new.threadpool.default_executor # => "It works"
