Crate spvirit_server 

PVAccess server library for EPICS.

Provides reusable server-side types, .db parsing, connection state, and the Source trait that abstracts over a PV data source. Consumers implement Source and register it with the SourceRegistry to serve PVs over PVAccess.

High-level API

use spvirit_server::{AnyPv, Pv, PvaServer};

let temp = Pv::ai("SIM:TEMP", 22.5).units("C").prec(2);
let sp = Pv::ao("SIM:SETPOINT", 25.0)
    .on_put(|_pv, v: f64| if v.is_finite() { Ok(()) } else { Err("NaN".into()) });

let server = PvaServer::serve([AnyPv::from(temp.clone()), AnyPv::from(sp)])
    .start()
    .await;
temp.set(23.1).await?;

// Classic builder (still supported):
let server = PvaServer::builder()
    .ai("SIM:TEMP", 22.5)
    .ao("SIM:SETPOINT", 25.0)
    .bo("SIM:ENABLE", false)
    .build();

server.run().await?;

Modules

apply

Functions that apply decoded PUT values to Normative Type payloads.

beacon

PVA beacon sender.

convert

Type conversions from DecodedValue to Rust scalars and ScalarValue.

db

decode

PUT body decoding utilities.

group

Group PV configuration: parse JSON definitions that compose multiple individual PVs into a single structured PVA channel.

handler

PVA protocol handler — the core TCP connection processor.

monitor

Monitor subscription management for the PVA server.

pv

Typed PV handles — the ergonomic front door to SimplePvStore.

pva_server

High-level PVAccess server — builder pattern for typed records.

pvstore

The Source trait — an object-safe abstraction over any PV data source, and SourceRegistry — a dynamic, priority-ordered collection of sources.

record_fields

IOC/QSRV-style record field access.

server

Top-level PVA server orchestration.

simple_store

A simple in-memory Source implementation backed by RecordInstance.

state

types

Server-specific record and IOC types.
