Pure processing logic. No threading concerns.

Required Methods

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.

Provided Methods

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 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<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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
