Struct ConfigWatcher 

pub struct ConfigWatcher { /* private fields */ }

A config file watcher that reloads on changes.

Uses notify for filesystem events and debounces rapid changes. Invalid config files are rejected — the last valid config is preserved.

Implementations

impl ConfigWatcher

pub fn new(path: impl AsRef<Path>) -> Result<Self, ConfigError>

Create a new ConfigWatcher for the given config file.

Loads the initial config from the file. Returns an error if the initial load fails.

pub fn subscribe(&self) -> Receiver<Arc<ForgeConfig>>

Get a receiver that yields the latest config on each change.

pub fn current(&self) -> Arc<ForgeConfig>

Get the current config.

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

Start watching the config file for changes.

Returns a JoinHandle for the background task. The task runs until the watcher is dropped or the file becomes unwatchable.
