Struct ImageProcessingOrchestrator 

pub struct ImageProcessingOrchestrator<'a> { /* private fields */ }

Main orchestrator for image processing operations.

This struct encapsulates the common patterns found across different processing methods, eliminating duplication while maintaining flexibility.

Implementations

impl<'a> ImageProcessingOrchestrator<'a>

pub fn new(oar_ocr: &'a OAROCR) -> Self

Create a new orchestrator with a reference to the OAROCR instance

pub fn process_batch<I>( &self, inputs: Vec<(usize, I)>, strategy: ProcessingStrategy, stage_config: PipelineStageConfig<'a>, ) -> Result<Vec<OAROCRResult>, OCRError>

where I: Into<ImageInputSource<'a>> + Send + Sync,

Process a batch of images with the specified strategy and configuration.

This method handles the common orchestration patterns:

• Parallel vs sequential processing decisions
• Index management and result sorting
• Progress logging and error handling

Arguments

• inputs - Vector of (index, input_source) pairs to process
• strategy - Processing strategy (sequential, parallel, or auto)
• stage_config - Configuration for pipeline stage execution

Returns

A Result containing a vector of OAROCRResult ordered by original index

pub fn process_single( &self, input: ImageInputSource<'a>, index: usize, stage_config: PipelineStageConfig<'a>, ) -> Result<OAROCRResult, OCRError>

Process a single image with the specified configuration.

This method provides a unified entry point for single image processing that can handle different input sources and pipeline configurations.

Arguments

• input - The image input source (path, memory, or pre-loaded)
• index - Index of this image in the batch (for logging and results)
• stage_config - Configuration for pipeline stage execution

Returns

A Result containing the OAROCRResult for this image
