copybook-error-reporter

Structured error reporting and handling for copybook-rs processing flows.

Overview

Provides configurable error accumulation with severity classification, strict/lenient handling policies, and summary statistics. Used by the codec and CLI layers to track and report errors across large batch processing runs without losing context on individual failures.

Usage

use copybook_error_reporter::{ErrorReporter, ErrorMode};

// Create a lenient reporter that continues on errors
let mut reporter = ErrorReporter::new(ErrorMode::Lenient, None);

// Report errors during processing; reporter accumulates them
// reporter.report_error(some_error);

let summary = reporter.summary();
println!("Processed with {} errors", summary.total_errors);
