Crate spvirit_client 

PVAccess client library — search, connect, get, put, monitor.

This crate provides both a high-level API (PvaClient) and the lower-level protocol functions used to build it.

High-level API

use spvirit_client::PvaClient;
use std::ops::ControlFlow;

let client = PvaClient::builder().build();

// GET
let result = client.pvget("MY:PV").await?;

// PUT
client.pvput("MY:PV", 42.0).await?;

// MONITOR
client.pvmonitor("MY:PV", |val| {
    println!("{val:?}");
    ControlFlow::Continue(())
}).await?;

// INFO (introspection)
let desc = client.pvinfo("MY:PV").await?;

Key types

• PvaClient — high-level client with pvget, pvput, pvmonitor, pvinfo
• PvOptions — configuration for PV operations (ports, timeout, auth)
• PvGetResult — decoded GET result with introspection
• ChannelConn — low-level established TCP channel
• SearchTarget — UDP/TCP search target address
