Struct HotReloadHandle 

pub struct HotReloadHandle { /* private fields */ }

Handle for controlling the hot-reload background thread.

Returned by HotReloadConfig::start_watching. Dropping the handle (or calling HotReloadHandle::stop) signals the worker to exit and tears down the kernel-level watch registration. Holding the handle keeps the watcher alive.

New handlers can be registered after start_watching via HotReloadHandle::on_change — the handler list is shared between the original HotReloadConfig and the spawned worker thread.

Implementations

impl HotReloadHandle

pub fn on_change<F>(&self, handler: F) -> Subscription

where F: Fn(&ConfigChangeEvent) + Send + Sync + 'static,

Register a change handler after start_watching has been called.

Semantics match HotReloadConfig::on_change. Useful when the consumer of the handle is a different component from whoever called start_watching — pass the handle around and let each component install its own handler.

pub fn stop(self) -> Result<()>

Stop the background watching thread.

Errors

Returns an error if the background thread panicked.

Trait Implementations

impl Drop for HotReloadHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
