to_string(), name: "alex", ts: 111}.print_me(); 就可以逐行打印出所有的Field了。 那么灵活的使用这个玩法,我们可以根据Struct的Field,自动生成 insert, update, delete的SQL也是可以的。给每个Field自动生成getter,setter方法…… (这个Java味太浓了,だめ) 研究这个是为了给 sqlx 增加一个自动生成insert...
fn main() { let person = Person::new("Alice".to_string(), 25); person.print_info(); } 在上面的代码中,我们使用new方法创建了一个名为person的Person实例,并使用print_info方法打印了该实例的信息。 这样,我们就在Rust中实现了特定类型的struct函数。通过实现结构体的方法,我们可以为结构体添加自定义...
