🛡️ Battle-Tested Resilience & Continuous Fuzzing `ebook-rs` is built to be the most resilient eBook engine in existence, specifically engineered to withstand the dirty long tail of corrupted, malformed, and non-spec files found across Project Gutenberg, Archive.org, and legacy digital archives: - **100% Graceful Error Guarantees**: Parsers **never panic** or crash on unexpected, malformed, or hostile inputs. Every format boundary validates lengths and magic bytes, returning `Result<Book, EbookError>`. - **Continuous Coverage-Guided Fuzzing**: Continuous LLVM `libFuzzer` (`cargo-fuzz`) runs mutate raw byte streams over millions of iterations against `Book::from_bytes` and CFI locators. - **Mass Corpus Stress Testing**: A dedicated chaos-testing runner (`examples/corpus_stress.rs`) evaluates real-world books across all 14 supported formats, injecting byte truncations (10% to 90%), zeroed headers, and bit-flipped noise. ### 📊 Real-World Resilience Scorecard | Test Suite / Corpus | Formats Evaluated | Ingestion Status | Panics / Crashes | Error Handling | | :--- | :--- | :--- | :--- | :--- | | **Real-World Sample Suite** | EPUB2, EPUB3, MOBI, AZW3, KFX, FB2, LIT, CBZ, PDF, DOCX, RTF, TXT | ✅ 100% Ingested | **0 Panics** | Graceful | | **Header Zeroing (16 bytes)** | All formats | ⚠️ Handled | **0 Panics** | Clean `Err(InvalidFormat)` | | **Truncation (10%, 25%, 50%, 90%)** | All formats | ⚠️ Handled / Repaired | **0 Panics** | Clean `Err(InvalidFormat)` | | **Bit-Flipped Noise Injection** | All formats | ⚠️ Handled / Resilient | **0 Panics** | Clean `Err` | | **Coverage-Guided Fuzzing (libFuzzer)** | Arbitrary byte streams | Millions of mutations | **0 Panics** | 100% Memory-Safe | #### Run the Automated Gutenberg Stress Test: ```bash # 1. Automatically fetch 25 Project Gutenberg classics: ./scripts/fetch_gutenberg.sh 25 corpus/gutenberg # Linux / macOS pwsh scripts/fetch_gutenberg.ps1 -Count 25 # Windows # 2. Run parallel resilience & chaos stress test: cargo run --release --all-features --example corpus_stress -- corpus/gutenberg # Or stress-test any local library directory: cargo run --release --all-features --example corpus_stress -- /path/to/your/ebooks ``` --- ## 📦 Installation Add `ebook-rs` to your `Cargo.toml`: ```toml [dependencies] ebook-rs = "0.16.6" ``` Or install via `cargo`: ```bash cargo add ebook-rs ``` For Python projects: ```bash pip install ebook-rs ``` --- ## 🚀 Quick Start (Rust) ```rust use ebook_rs::{Book, SearchEngine, RagChunkConfig}; fn main() -> Result<(), Box<dyn std::error::Error>> { // 1.
