purpurea

此包提供基于属性的便利方法生成（访问器/更新器/修改器/构造函数）用于具有私有字段的 struct。该包的属性宏实现的观察结果与 Java 库 Lombok 的 @Getter/@Setter 和 @RequiredArgsConstructor/@AllArgsConstructor 注解的结果有些相似，带有 Rust 风格。

示例

mod examples {
    use purpurea::*;
    
    #[accessors(email)]
    #[updaters(email)]
    #[default_constructor]
    pub struct User {
        email: String,
        account_number: usize
    }
}
     
use examples::*;

let john_doe = User::new("[email protected]", 45275);
let new_email = "[email protected]";
let john_doe2 = john_doe.with_email(new_email.to_owned());

assert_eq!(new_email, john_doe2.email());
