Struct MeterStore 

pub struct MeterStore { /* private fields */ }

Fixed array of f32-bit atomic meter slots, indexed by meter id.

Writers (the shells’ meter_fn, called from process()) and readers (editor get_meter closures) address slots by the meter’s param-space id (METER_ID_BASE + index); ids outside the slot range read as 0.0 and write as a no-op, so a stale or out-of-range id can’t panic on either thread.

Implementations

impl MeterStore

pub fn new() -> Arc<Self>

pub fn read(&self, meter_id: u32) -> f32

Read the meter value for meter_id. 0.0 for ids outside the slot range.

pub fn write(&self, meter_id: u32, value: f32)

Publish the meter value for meter_id. No-op for ids outside the slot range.
