Crate epics_libcom_rs 

EPICS libCom for Rust: the layer an IOC is built on, with no record system above it.

This is epics_base_rs::runtime and epics_base_rs::net lifted out of epics-base-rs (issue #55) so a consumer — a protocol client, a gateway, pvxs-rs — can take the concurrency and socket primitives without taking the database with them. The name is C’s: libCom is where upstream EPICS keeps epicsThread, epicsTime, errlog, envDefs and osiSock, which is exactly this crate’s two modules.

epics-base-rs re-exports both modules at their original paths, so epics_base_rs::runtime::… and epics_base_rs::net::… still resolve and nothing downstream had to change.

• runtime — the task seam and its two backends, epicsThread-parity priority bands, errlog, the EPICS string/environment types, the general-time provider.
• net — the EPICS protocols’ shared socket layer: per-NIC async UDP, interface enumeration, loopback multicast. Host-only; the wire constants beside it compile for every target, RTEMS included.
• walltime — WallTime, the wall-clock instant runtime::time returns. It lived in epics_base_rs::types and moved down with its producer; epics-base-rs re-exports it at types::WallTime.

Features

• rtems-exec-model — select the reactor-free exec_backend on a hosted target. See EXEC_BACKEND.
• linux-rt — back runtime::sync::PriorityInheritanceMutex with a PTHREAD_PRIO_INHERIT pthread_mutex_t on Linux.

Modules

net

Cross-platform networking primitives shared by epics-ca-rs, epics-pva-rs, and epics-bridge-rs.

runtime

The concurrency, timing, logging and OS-facing primitives an IOC is built on — C libCom’s epicsThread / epicsTime / errlog / envDefs half.

walltime

WallTime — a wall-clock instant with full EPICS nanosecond precision on every platform.

Macros

rt_debug

Debug-level runtime log line. Routes through the tracing facade.

rt_error

Error-level runtime log line. Routes through the tracing facade.

rt_info

Info-level runtime log line. Routes through the tracing facade.

rt_warn

Warn-level runtime log line. Routes through the tracing facade.

Constants

EXEC_BACKEND

Which runtime::task backend this build selected — true for the reactor-free std-thread runtime::background executor, false for tokio.
