Getting Started

Prerequisites

# Install Rust (if not already installed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Update Rust to latest stable
rustup update stable

Building Projects

Each project can be built independently:

# Navigate to a project directory
cd web_crawler_pdf

# Build in release mode for optimal performance
cargo build --release

# Run the program
cargo run --release -- [arguments]

Example: Running the PDF Web Crawler

cd web_crawler_pdf
cargo run --release -- \
    --url "https://example.com" \
    --depth 3 \
    --concurrency 10 \
    --output pdfs.json \
    --verify

Example: Running File Search

# For standalone .rs files in examples/
rustc examples/file_searchv6.rs
./file_searchv6 /path/to/search "*.txt"
