Struct Refreshable 

pub struct Refreshable<T> { /* private fields */ }

A wrapper that auto-refreshes its value when configuration changes. 在配置更改时自动刷新其值的包装器。

Equivalent to Spring Cloud’s @RefreshScope bean behavior. 等价于 Spring Cloud 的 @RefreshScope bean 行为。

Example / 示例

use hiver_config::refresh::Refreshable;

let mut port = Refreshable::new("server.port", 8080);
assert_eq!(*port.get(), 8080);

port.update("9090".to_string());
assert_eq!(*port.get(), 9090);
