Rust还提供了 "类元组结构",这是有编号而非命名字段的结构体。 structMyTuple(pub u32,pub u8); 复制 字段的访问采用类似的点状语法:tuple.0, tuple.1,并采用类似函数调用的语法构造:MyTuple(1, 2)。除了语法之外,它们与普通结构体没有区别。类元组结构上的字段可以省略,以声明一个零字节的结构。 struct M...
介绍如何配置CX11x&CX31x&CX91x系列交换模块的各类业务,从配置实例和功能配置两大方面介绍了业务的配置过程。 原理描述 基本原理 自动部署的方式及典型组网环境 当设备的配置恢复模式为非同步模式时,空配置的设备在上电后自动进入ZTP流程。设备尝试通过DHCP方式完成自动部署。详细的工作流程请参见ZTP详细工作流程。

This implementation of rotating a ten-element array up by five positions (Figure 1) is from Doug Mcllroy; try it. The reversal code is time- and space-efficient, and is so short and simple that it's pretty hard to get wrong. It is exactly the code that Kernighan and Plauger use in ...
