Ruby 模块声明 [英] Ruby Module Declaration

问题描述

做有什么区别吗

class Bus::Driver
end

和

module Bus
  class Driver
  end
end

如果不是，首选哪种语法?

If not, which syntax is preferred?

推荐答案

做 [...] 有什么区别吗?

Is there any difference between doing [...]?

唯一的区别是在class Bus::Driver中Bus模块必须已经定义，而相同并不代表第二个.

The only difference is that in class Bus::Driver the Bus module must be already defined, while the same does not stand for the second.

首选哪种语法?

这不是一个建设性的问题，但我个人更喜欢第二个，因为它明确指出 Bus 是一个模块，而第一个我第一眼看不到 Bus> 是一个模块或一个类.

This is not a constructive question but I personally prefer the second because it states explicitly that Bus is a module, while with the first I cannot see at first glance if Bus is a module or a class.
