Struct ShutdownSignal 

pub struct ShutdownSignal { /* private fields */ }

One-way “stop now” signal, observable by any number of tasks.

A latched flag rather than a bare Notify: a task that checks after the signal fired must still see it, or a worker between two units would sleep through the daemon’s exit and hold the store open.

Implementations

impl ShutdownSignal

pub fn new() -> Self

pub fn trigger(&self)

Ask everything watching to stop. Idempotent.

pub fn is_triggered(&self) -> bool

pub async fn wait(&self)

Resolve when shutdown is requested — immediately if it already was.

pub async fn guard<F: Future>(&self, future: F) -> Option<F::Output>

Run future unless shutdown arrives first. None means it did.

pub async fn sleep_until_stopped(&self, duration: Duration) -> bool

Sleep for duration. true means shutdown cut it short.

Trait Implementations

impl Debug for ShutdownSignal

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

Formats the value using the given formatter.

impl Default for ShutdownSignal

fn default() -> ShutdownSignal

Returns the “default value” for a type.
