@return 函数返回值注解

注解

利用 @return 注解来标记函数的返回值类型

• 完整格式：

---@return MY_TYPE[|OTHER_TYPE] [@comment]

• 应用目标：

  • 函数

  ---@return Car|Ship
  local function create()
      ...
  end
  
  ---Here car_or_ship doesn't need @type annotation, EmmyLua has already inferred the type via "create" function
  local car_or_ship = create()
  

  ---@return Car
  function factory:create()
      ...
  end
