Crate kreuzberg 

Kreuzberg - High-Performance Document Intelligence Library

Kreuzberg is a Rust-first document extraction library with language-agnostic plugin support. It provides fast, accurate extraction from PDFs, images, Office documents, emails, and more.

Quick Start

use kreuzberg::{extract_file_sync, ExtractionConfig};

// Extract content from a file
let config = ExtractionConfig::default();
let result = extract_file_sync("document.pdf", None, &config)?;
println!("Extracted: {}", result.content);

Architecture

• Core Module (core): Main extraction orchestration, MIME detection, config loading
• Plugin System: Language-agnostic plugin architecture
• Extractors: Format-specific extraction (PDF, images, Office docs, email, etc.)
• OCR: Multiple OCR backend support (Tesseract, EasyOCR, PaddleOCR)

Features

• Fast parallel processing with async/await
• Priority-based extractor selection
• Comprehensive MIME type detection (118+ file extensions)
• Configurable caching and quality processing
• Cross-language plugin support (Python, Node.js planned)
