ShutdownSignal

cadmus_core::task

Struct ShutdownSignal 

Source 
pub struct ShutdownSignal {
    receiver: Receiver<()>,
    stopped: AtomicBool,
}
Expand description

Signal for coordinating graceful shutdown of background tasks.

Tasks should periodically check should_stop or use wait to interrupt sleep when shutdown is requested.

Fields§

§receiver: Receiver<()>§stopped: AtomicBool

Implementations§

Source§

impl ShutdownSignal

Source

fn new(receiver: Receiver<()>) -> Self

Source

pub fn should_stop(&self) -> bool

Returns true if shutdown has been requested.

Once true is returned, all subsequent calls also return true (the shutdown state is latched). This is non-blocking and suitable for polling in tight loops.

Source

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

Waits for the given duration or until shutdown is requested.

Returns true if shutdown was requested, false if the duration elapsed.

This is the preferred method for tasks that sleep between work cycles.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

fn into_any_send(self: Box<T>) -> Box<dyn Any + Send>
