Struct ScatterProcessor 

pub struct ScatterProcessor { /* private fields */ }

Scatter processor: distributes arrays to downstream plugins in round-robin order.

The actual number of downstream consumers is discovered by the plugin runtime, which publishes a scatter result to scatter_index % senders.len(). num_outputs == 0 (the default) means “use the live downstream count”: the processor emits a raw incrementing index and the runtime maps it onto the connected consumers — equivalent to C++ NDPluginScatter advancing nextScatter over its registered clients. A non-zero num_outputs caps the round-robin span for tests / fixed fan-out.

Implementations

impl ScatterProcessor

pub fn new() -> Self

pub fn set_num_outputs(&mut self, n: usize)

Override the round-robin span. 0 means “use the live downstream consumer count” (the default).

Trait Implementations

impl Default for ScatterProcessor

fn default() -> Self

Returns the “default value” for a type.

impl NDPluginProcess for ScatterProcessor

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.
