Struct AttrPlotProcessor 

pub struct AttrPlotProcessor { /* private fields */ }

Processor that tracks attribute values over time in circular buffers.

Implementations

impl AttrPlotProcessor

pub fn new(n_attributes: usize, cache_size: usize, n_data_blocks: usize) -> Self

Create a processor.

• n_attributes — maximum tracked attributes.
• cache_size — per-buffer cache size (0 = unlimited).
• n_data_blocks — number of waveform output blocks.

pub fn attributes(&self) -> &[String]

Get the list of tracked attribute names.

pub fn buffer(&self, index: usize) -> Option<&VecDeque<f64>>

Get the circular buffer for a specific attribute index.

pub fn uid_buffer(&self) -> &VecDeque<f64>

Get the unique_id buffer.

pub fn num_attributes(&self) -> usize

Get the number of tracked attributes.

pub fn num_data_blocks(&self) -> usize

Get the number of waveform output blocks.

pub fn find_attribute(&self, name: &str) -> Option<usize>

Find the index of a named attribute. Returns None if not tracked.

pub fn data_select(&self, block: usize) -> Option<i32>

Current DataSelect value for a block.

pub fn set_data_select( &mut self, block: usize, value: i32, ) -> Result<(), &'static str>

Bind a data block to an attribute index (or a UID/NONE sentinel).

Mirrors C++ writeInt32(NDAttrPlotDataSelect): rejects out-of-range blocks and selections that point past the tracked attributes.

pub fn data_label(&self, block: usize) -> String

The DataLabel text for a block, derived from its DataSelect.

pub fn reset(&mut self)

Reset all buffers; the next frame re-discovers attributes.

Trait Implementations

impl NDPluginProcess for AttrPlotProcessor

fn process_array( &mut self, array: &NDArray, _pool: &NDArrayPool, ) -> ProcessResult

Process one array. Return output arrays and param updates.

fn plugin_type(&self) -> &str

Plugin type name for PLUGIN_TYPE param.

fn register_params(&mut self, base: &mut PortDriverBase) -> AsynResult<()>

Register plugin-specific params on the base. Called once during construction.

fn on_param_change( &mut self, reason: usize, params: &PluginParamSnapshot, ) -> ParamChangeResult

Called when a param changes. Reason is the param index. Return param updates to be written back to the port driver.

fn compression_aware(&self) -> bool

Whether this plugin can process compressed (codec != None) arrays (C++ compressionAware_, G3). Defaults to false: a plugin that operates on raw pixels must not be handed compressed bytes — the runtime drops compressed input and counts it into DroppedArrays. A codec/file plugin that understands compressed data overrides this.

fn array_data_handle( &self, ) -> Option<Arc<Mutex<RawMutex, Option<Arc<NDArray>>>>>

Return a handle to the latest NDArray data for array reads. Override this in plugins like NDPluginStdArrays that serve pixel data via readInt8Array/readInt16Array/etc.
