Struct ChannelStore 

pub struct ChannelStore { /* private fields */ }

Central channel value storage shared between monitor callbacks and state sets.

Each channel has its own Mutex<ChannelValueSlot>. Contention is low because monitors write rarely and state sets read only during sync.

Implementations

impl ChannelStore

pub fn new(num_channels: usize) -> Self

pub fn set(&self, ch_id: usize, value: EpicsValue)

Update a channel’s value (called from monitor callback or pvGet).

pub fn set_full( &self, ch_id: usize, value: EpicsValue, status: i16, severity: i16, )

Update a channel’s value with status/severity.

pub fn get(&self, ch_id: usize) -> Option<EpicsValue>

Read a channel’s current value.

pub fn get_full(&self, ch_id: usize) -> Option<ChannelValueSlot>

Read a channel’s full slot (value + metadata).

pub fn num_channels(&self) -> usize
