这样就可以通过cargo add来向项目中简化添加依赖项，比如添加num，就执行cargo add num就行：
liujianhuadeiMac:samp2_3 liujianhua$ cargo add num
Updating crates.io index
Adding num v0.4.1 to dependencies.
Features:
+ std
- alloc
- libm
- num-bigint
- rand
- serde
Updating crates.io index
向项目中添加num::complex::Complex后，编译运行程序后如下：
这样以后，添加第三方依赖就简单多了。
