Defining Data

Thread Safety

The data field is not thread-safe, which means that Quebec can't ensure integrity of the data as it might be accessed by multiple threads at once. We might introduce a solution to this in the future using locks, but for now you have to use workarounds.

Sometimes you want your singletons to store data which changes overtime. To avoid your data from being overwritten by accident from Quebec, you can use the data field within your singleton. The framework will NEVER touch the data field and therefore your data is safe there.

Example Service Using The Data Field

local Service = {
    lifecycles = { "start", "onStep" },
    data = {
        counter = 0
    }
}

function Service:start()
    print("Counter is:", self.data.counter)
end

function Service:onStep(_dt)
    self.data.counter += 1
    
    print(self.data.counter)
end

return Service
