我们可以在一个结构体实例里面使用..otherStruct来对otherStruct里面未被定义的变量原封不动解包到该结构体实例里面

structs2.rs

Rust),count:1,..order_template};assert_eq!(your_order.name,

Hacker

Rust);assert_eq!(your_order.year,

order_template.year);assert_eq!(your_order.made_by_phone,

order_template.made_by_phone);assert_eq!(your_order.made_by_mobile,

order_template.made_by_mobile);assert_eq!(your_order.made_by_email,

order_template.made_by_email);assert_eq!(your_order.item_number,

order_template.item_number);assert_eq!(your_order.count,

1);}

}33.类里面的方法除了当前区域内的变量,其他都要加self引用
