<- Stdlib Reference | Language Guide | Detailed reference
High-level networking patterns built over NNG transport primitives.
For local PID and mailbox messaging inside one Eta runtime, use std.actor.
For distributed actor nodes over the same NNG transport layer, use
std.actor.node.
Build flag: Available only when Eta is built with
-DETA_BUILD_NNG=ON.
(import std.net)
| Symbol | Description |
|---|---|
(nng-monitor socket) | Register socket disconnect monitoring for recv! down messages. |
(nng-demonitor socket) | Remove socket disconnect monitoring. |
(with-socket spec thunk) | Open a socket, run thunk with it bound, close on exit. |
(request-reply endpoint message) | Open a REQ socket, send one message, receive one reply, close. |
(worker-pool module-path tasks) | Spawn one child per task and collect one reply per child in submission order. |
(pub-sub endpoint topics handler) | Connect a SUB socket, subscribe to each topic, and invoke handler per message. |
(survey endpoint question timeout-ms) | Open a SURVEYOR socket, send one question, collect replies until timeout. |
worker-pool is a compatibility helper over socket-based child workers. Each
worker module is expected to use:
(recv! (current-mailbox) 'wait)to read one task(send! (current-mailbox) result 'wait)to return one result
std.actor / std.actor.node operate on actor PIDs and node handshakes.
std.net exposes raw socket workflows and explicit socket monitoring via
nng-monitor / nng-demonitor.
