Module errors 

Error types for the OCR pipeline.

Provides OCRError (the pipeline-wide error type), ProcessingStage (which stage an error occurred in), and helper constructors for building errors with context and chaining.

Usage

use oar_ocr_core::core::errors::{OCRError, ProcessingStage};

// Create a processing error with context
let error = OCRError::tensor_operation(
    "Failed to reshape tensor for batch processing",
    std::io::Error::new(std::io::ErrorKind::InvalidData, "Invalid tensor shape")
);

// Create a configuration error
let config_error = OCRError::config_error("Missing required model path");

// Create a validation error with detailed context
let validation_error = OCRError::validation_error(
    "TextDetector",
    "input_size",
    "[640, 640]",
    "[320, 320]"
);

Structs

OpaqueError

A simple, opaque error wrapper for cases where the original error type is not Send or doesn’t implement std::error::Error.

Enums

ImageProcessError

Errors that can occur during image processing operations.

OCRError

Enum representing various errors that can occur in the OCR pipeline.

ProcessingStage

Enum representing different stages of processing in the OCR pipeline.

Type Aliases

OcrResult

Convenient result alias for OCR operations.
