Struct PvaChannel 

pub struct PvaChannel { /* private fields */ }

A persistent PVA channel for high-rate streaming PUT operations.

Created via PvaClient::open_put_channel, this keeps the TCP connection open and reuses the PUT introspection for repeated writes without per-operation handshake overhead.

Example

let client = PvaClient::builder().build();
let mut channel = client.open_put_channel("MY:PV").await?;
for value in 0..100 {
    channel.put(value as f64).await?;
}

Implementations

impl PvaChannel

pub async fn put(&mut self, value: impl Into<Value>) -> Result<(), PvGetError>

Write a value over the persistent channel.

Automatically sends echo keepalive pings when more than 10 seconds have elapsed since the last one.

pub fn introspection(&self) -> &StructureDesc

Returns the PUT introspection for this channel.
