Goldboot
goldboot 是一款用于为真实硬件构建机器镜像的工具，能够实现接近不可变的基础设施，而无需进行大量额外的工作。
在 Goldboot 的方法中，可以为每台部署的计算机创建一个声明性配置文件。利用这个配置文件，Goldboot 可以在本地计算机或 CI 平台（如 Github Actions）上构建镜像。生成的镜像可以通过 USB 驱动器或 PXE 启动部署到实际硬件上。

示例代码语言：javascript，运行次数：0
fn main() {
let validator = Validator::new()
.rule("name", Required.and(StartWith("hello")))
.rule("age", custom(age_limit))
.message([
("name.required", "name is required"),
("name.start_with", "name should be starts with `hello`"),
]);
let person = Person {
name: "li",
age: 18,
};
let res = validator.validate(person);
// or using trait
let res = person.validate(validator);
}
fn age_limit(n: &mut u8) -> Result {
