Struct ConfigWatcher 

pub struct ConfigWatcher<T: HotConfig> { /* private fields */ }

Configuration watcher that automatically reloads config on file changes

Features:

• Automatic reload on file changes
• Debouncing to prevent excessive reloads
• Validation before applying
• Atomic updates with arc-swap
• Error recovery (keeps previous config on failure)

Implementations

impl<T: HotConfig> ConfigWatcher<T>

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self>

Create a new config watcher with default debounce duration (500ms)

pub fn with_debounce<P: AsRef<Path>>( path: P, debounce: Duration, ) -> Result<Self>

Create a new config watcher with custom debounce duration

Debouncing prevents excessive reloads when a file is modified multiple times in quick succession (common with text editors).

pub fn get(&self) -> Arc<T>

Get the current configuration

pub fn reload(&self) -> Result<()>

Manually reload the configuration

pub fn path(&self) -> &Path

pub fn debounce_duration(&self) -> Duration

Get the debounce duration

pub fn time_since_last_reload(&self) -> Duration

Get the time since last reload
