Struct Child 

pub struct Child<E, C = dyn AnyChannel>
where
    E: Send + 'static,
    C: DynChannel + ?Sized,
{ /* private fields */ }

A child is the non clone-able reference to an actor with a single process.

Children can be of two forms:

• Child<E, Channel<M>>: This is the default form, it can be transformed into a Child<E> using Child::into_dyn.
• Child<E>: This form is a dynamic child, it can be transformed back into a Child<E, Channel<M>> using Child::downcast::.

A child can be transformed into a ChildPool using Child::into_pool().

A child can be awaited which returns the parameter E once the actor exits.

Implementations

impl<E, C> Child<E, C>

where E: Send + 'static, C: DynChannel + ?Sized,

pub fn into_joinhandle(self) -> JoinHandle<E>

Get the underlying JoinHandle.

This will not run the drop, and therefore the actor will not be halted/aborted.

pub fn abort(&mut self) -> bool

Abort the actor.

Returns true if this is the first abort.

pub fn is_finished(&self) -> bool

Whether the task is finished.

pub fn into_pool(self) -> ChildPool<E, C>

Convert the Child into a ChildPool.

pub fn downcast<M: Send + 'static>(self) -> Result<Child<E, Channel<M>>, Self>

where C: AnyChannel,

Downcast the Child<E> to a Child<E, Channel<M>>.

pub fn shutdown(&mut self, timeout: Duration) -> ShutdownFut<'_, E, C>

Halts the actor, and then waits for it to exit. This always returns with the result of the task, and closes the channel.

If the timeout expires before the actor has exited, the actor will be aborted.

pub fn get_address(&self) -> Address<C>

Get a new Address to the Channel.

pub fn attach(&mut self, duration: Duration) -> Option<Duration>

Attach the actor.

Returns the old abort-timeout if it was already attached.

pub fn detach(&mut self) -> Option<Duration>

Detach the actor.

Returns the old abort-timeout if it was attached before.

pub fn is_aborted(&self) -> bool

Whether the actor is aborted.

pub fn is_attached(&self) -> bool

Whether the actor is attached.

pub fn link(&self) -> &Link

Get a reference to the current Link of the actor.

pub fn close(&self) -> bool

Close the Channel.

pub fn halt(&self)

Halt the actor.

This also closes the Inbox.

pub fn halt_some(&self, n: u32)

Halt n processes.

pub fn process_count(&self) -> usize

Get the amount of processes.

pub fn msg_count(&self) -> usize

Get the amount of messages in the Channel.

pub fn address_count(&self) -> usize

Get the amount of Addresses of the Channel.

pub fn is_closed(&self) -> bool

Whether the Channel is closed.

pub fn is_bounded(&self) -> bool

pub fn capacity(&self) -> &Capacity

Get the Capacity of the Channel.

pub fn has_exited(&self) -> bool

Whether all processes have exited.

pub fn actor_id(&self) -> u64

Get the actor’s id.

impl<E, M> Child<E, Channel<M>>

where E: Send + 'static, M: Send + 'static,

pub fn into_dyn(self) -> Child<E>

Convert the Child<T, Channel<M>> into a Child<T>

pub fn try_send(&self, msg: M) -> Result<(), TrySendError<M>>

Attempt to send a message to the actor.

• In the case of an unbounded Channel, when BackPressure returns a timeout this fails.
• In the case of a bounded Channel, when it is full this fails.

For bounded channels, this method is the same as send_now.

pub fn send_now(&self, msg: M) -> Result<(), TrySendError<M>>

Attempt to send a message to the actor.

• In the case of an unbounded Channel, any BackPressure is ignored.
• In the case of a bounded Channel, when it is full this fails.

For bounded channels, this method is the same as try_send.

pub fn send(&self, msg: M) -> SendFut<'_, M>

Attempt to send a message to the actor.

• In the case of an unbounded Channel, when BackPressure returns a timeout this waits untill the timeout is over.
• In the case of a bounded Channel, when it is full this waits untill space is available.

pub fn send_blocking(&self, msg: M) -> Result<(), SendError<M>>

Same as send but it blocking the OS-thread.

Trait Implementations

impl<E, C> Debug for Child<E, C>

where E: Send + 'static + Debug, C: DynChannel + ?Sized + Debug,

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

Formats the value using the given formatter.

impl<E: Send + 'static, C: DynChannel + ?Sized> Drop for Child<E, C>

fn drop(&mut self)

Executes the destructor for this type.

impl<E: Send + 'static, C: DynChannel + ?Sized> Future for Child<E, C>

type Output = Result<E, ExitError>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
