Implementations

impl<T: Clone + Send + Sync + 'static> ConfigReloader<T>

pub fn new( config: ReloaderConfig, shared: SharedConfig<T>, reload_fn: impl Fn() -> Result<T, Box<dyn Error + Send + Sync>> + Send + Sync + 'static, validate_fn: impl Fn(&T) -> Result<(), Box<dyn Error + Send + Sync>> + Send + Sync + 'static, ) -> Self

Create a new config reloader.

• config: Reload trigger configuration
• shared: Shared config to update on successful reload
• reload_fn: Called to load a fresh config (re-reads file + env)
• validate_fn: Called to validate before applying (return Err to reject)

pub fn with_post_reload_hook( self, hook: impl Fn(&T) + Send + Sync + 'static, ) -> Self

Add a hook that runs after each successful reload.

Use this to connect to the config registry:

// reloader.with_registry_update("my_app");

pub fn with_registry_update(self, key: &str) -> Self

where T: Serialize + Default,

Connect to the config registry: after each successful reload, call registry::update() so listeners are notified and the registry reflects the new effective config.

Requires T: Serialize + Default.

pub fn start(self) -> JoinHandle<()>

Start the reload loop in a background task.

Returns a JoinHandle that can be used to abort the reloader. The task runs until cancelled or the process exits.
