Struct PvArray 

pub struct PvArray { /* private fields */ }

Handle to an array-backed record (waveform/aai/aao). Unlike Pv<T> this is untyped over the element kind — values are ScalarArrayValue. Cheap to clone; all clones share state.

Implementations

impl PvArray

pub fn waveform(name: impl Into<String>, data: ScalarArrayValue) -> Self

waveform — array record, writable over the wire.

pub fn aai(name: impl Into<String>, data: ScalarArrayValue) -> Self

aai — analog array input, read-only over the wire.

pub fn aao(name: impl Into<String>, data: ScalarArrayValue) -> Self

aao — analog array output, writable over the wire.

pub fn name(&self) -> &str

pub async fn set(&self, data: ScalarArrayValue) -> Result<(), PvError>

Write an array value through the full posting pipeline.

pub async fn set_alarm( &self, severity: i32, status: i32, message: &str, ) -> Result<(), PvError>

Explicitly set the record’s alarm severity/status/message, independent of its value. Alarm transitions always post (no MDEL gating, no link evaluation). A no-op re-set (unchanged alarm) is Ok(()).

pub async fn get(&self) -> Result<ScalarArrayValue, PvError>

Read the current array value.

Trait Implementations

impl Clone for PvArray

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<PvArray> for AnyPv

fn from(pv: PvArray) -> Self

Converts to this type from the input type.
