字面量类型

Note

字面量类型（String literal types）允许你指定字符串作为固定的代码提示，结合 @alias 特性可以起到类似“枚举”的效果

• 示例

  ---@alias Handler fun(type: string, data: any):void
  
  ---@param event string | "'onClosed'" | "'onData'"
  ---@param handler Handler | "function(type, data) print(data) end"
  function addEventListener(event, handler)
  end
  

  

  
  

  

  
  

  Note

  建议使用 @alias 简化类型复杂度

  ---@alias Handler fun(type: string, data: any):void
  
  ---@alias IOEventEnum string | "'onClosed'" | "'onData'"
  
  ---@param event IOEventEnum
  ---@param handler Handler | "function(type, data) print(data) end"
  function addEventListener(event, handler)
  end
