Variants

StartWorker

Fields

addrs: Vec<Address>

The set of addresses in use by this worker

senders: SenderPair

Pair of senders to the worker relay (msgs and ctrl)

detached: bool

A detached context/ “worker” runs no relay state

mailbox_count: Arc<AtomicUsize>

A mechanism to read channel fill-state for a worker

reply: SmallSender<NodeReplyResult>

Reply channel for command confirmation

Start a new worker and store the send handle

ListWorkers(SmallSender<NodeReplyResult>)

Return a list of all worker addresses

SetCluster(Address, String, SmallSender<NodeReplyResult>)

Add an existing address to a cluster

StopWorker(Address, bool, SmallSender<NodeReplyResult>)

Stop an existing worker

StartProcessor(Address, SenderPair, SmallSender<NodeReplyResult>)

Start a new processor

StopProcessor(Address, SmallSender<NodeReplyResult>)

Stop an existing processor

StopNode(ShutdownType, SmallSender<NodeReplyResult>)

Stop the node (and all workers)

AbortNode

Immediately stop the node runtime

StopAck(Address)

Let the router know a particular address has stopped

SenderReq(Address, SmallSender<NodeReplyResult>)

Request the sender for a worker address

Router(TransportType, Address, SmallSender<NodeReplyResult>)

Register a new router for a route id type

SetReady(Address)

Message the router to set an address as “ready”

CheckReady(Address, SmallSender<NodeReplyResult>)

Check whether an address has been marked as “ready”

Implementations

impl NodeMessage

pub fn start_worker(
    addrs: Vec<Address>,
    senders: SenderPair,
    detached: bool,
    mailbox_count: Arc<AtomicUsize>
) -> (Self, SmallReceiver<NodeReplyResult>)

Create a start worker message

• senders: message and command senders for the relay

• detached: indicate whether this worker address has a full relay behind it that can respond to shutdown commands. Setting this to true will disable stop ACK support in the router

pub fn start_processor(
    address: Address,
    senders: SenderPair
) -> (Self, SmallReceiver<NodeReplyResult>)

Create a start worker message

pub fn stop_processor(
    address: Address
) -> (Self, SmallReceiver<NodeReplyResult>)

Create a stop worker message and reply receiver

pub fn list_workers() -> (Self, SmallReceiver<NodeReplyResult>)

Create a list worker message and reply receiver

pub fn set_cluster(
    addr: Address,
    label: String
) -> (Self, SmallReceiver<NodeReplyResult>)

Create a set cluster message and reply receiver

pub fn stop_worker(
    address: Address,
    detached: bool
) -> (Self, SmallReceiver<NodeReplyResult>)

Create a stop worker message and reply receiver

pub fn stop_node(tt: ShutdownType) -> (Self, SmallReceiver<NodeReplyResult>)

Create a stop node message

pub fn sender_request(route: Address) -> (Self, SmallReceiver<NodeReplyResult>)

Create a sender request message and reply receiver

pub fn set_ready(addr: Address) -> Self

Create a SetReady message and reply receiver

pub fn get_ready(addr: Address) -> (Self, SmallReceiver<NodeReplyResult>)

Create a GetReady message and reply receiver
