Struct PosPluginProcessor 

pub struct PosPluginProcessor { /* private fields */ }

NDPosPlugin processor: attaches position metadata to arrays from a position list.

Implementations

impl PosPluginProcessor

pub fn new(mode: PosMode) -> Self

pub fn load_positions_json(&mut self, json_str: &str) -> Result<usize, Error>

Load positions from a JSON string.

pub fn load_positions_xml(&mut self, xml_str: &str) -> Result<usize, String>

Load positions from an XML string (C++ NDPosPlugin format).

Expected XML format:

<positions>
  <position index="0">value1</position>
  <position index="1">value2</position>
</positions>

Each <position> element becomes a single-entry HashMap with key “position” mapped to the parsed f64 value. If the value cannot be parsed as f64, the position is skipped.

pub fn load_positions_auto(&mut self, content: &str) -> Result<usize, String>

Load positions from a string, auto-detecting format.

If the content starts with ‘<’ (after trimming whitespace), it is treated as XML. Otherwise, it is treated as JSON.

pub fn load_positions(&mut self, positions: Vec<HashMap<String, f64>>)

Load positions directly.

pub fn start(&mut self)

Start processing.

pub fn stop(&mut self)

Stop processing.

pub fn clear(&mut self)

Clear all positions.

pub fn missing_frames(&self) -> usize

pub fn duplicate_frames(&self) -> usize

pub fn remaining_positions(&self) -> usize

Trait Implementations

impl NDPluginProcess for PosPluginProcessor

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, ) -> Result<(), AsynError>

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 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.
