Struct Watcher 

pub struct Watcher { /* private fields */ }

A running watcher. Dropping it signals the thread to stop and joins it.

Implementations

impl Watcher

pub fn spawn(config: Config) -> Option<Watcher>

Start the watcher unless disabled by config or RAG_RAT_NO_WATCH. The returned watcher must be kept alive; dropping it stops the thread. Returns None when watching is disabled.

pub fn spawn_with_fleet( config: Config, fleet_bin: Option<PathBuf>, ) -> Option<Watcher>

Like Watcher::spawn, but when fleet_bin is the installed-binary path, the elected watcher also watches that file’s directory and signals the hot-upgrade fleet (see crate::fleet) when a new binary lands. Only the MCP server — which has a SIGUSR1 handler — passes Some.

Trait Implementations

impl Debug for Watcher

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Watcher

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.
