Distributed actor-node transport helpers over NNG.
(import std.actor.node)
std.actor.node manages node handshake and routing. It is complementary to:
std.actorfor PID/mailbox actor APIsstd.netfor raw transport socket workflows
| Symbol | Description |
|---|---|
(node-name) | Return local node name used in handshake metadata. |
(monitor-node node-name) | Monitor one remote node name; returns monitor ref. |
(node-listen endpoint . opts) | Start listening for one remote node on endpoint. |
(node-connect endpoint . opts) | Connect to one remote node endpoint. |
(nodes) | Return connected node entries (node-name node-id endpoint). |
(disconnect-node node-name) | Disconnect one node by name. |
Supported node-listen / node-connect options:
'node-nameor'name(string or symbol)'cookie(string or symbol)
When overriding node identity with options, provide both node-name/name
and cookie in the same call.
Node monitor messages:
'(nodeup ref node-name node-id)
'(nodedown ref node-name reason)
Distributed monitor and netsplit semantics:
- Remote process monitors deliver one
'(DOWN ref process pid reason)message. - Node loss uses reason
'noconnectionfor remote processDOWNdelivery. - Node monitor
nodedownuses reason'noconnectionon disconnect and'bad-cookieon rejected cookie handshakes. demonitorwith flush (#t) removes queued monitor events for that ref, including remoteDOWNand node monitor lifecycle messages.
