字面量类型¶
注解
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
注解
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
