## What it is
A Rust library and command-line tool for generating fake data such as names, addresses, dates, and internet identifiers across 13 locales. It offers type-safe generation via a #[derive(Dummy)] macro, seeded RNGs for reproducibility, and integrations with popular crates like chrono, uuid, and serde_json.

## Use cases
- generate fake test data in Rust
- seed a database with realistic dummy records
- generate random names and addresses for unit tests
- create reproducible mock datasets with a seeded RNG
- generate fake data from the command line
- populate fixtures with localized fake data in multiple languages
- generate fake UUIDs, dates, and JSON for API testing

## When to choose
- You need type-safe, locale-aware fake data generation inside Rust code or tests
- You want reproducible test data via seeded RNGs
- You need a quick CLI to emit fake values like names, IPs, or credit card numbers

## When to avoid
- You are not working in Rust and need a general-purpose faker for another language
- You need production-grade realistic data rather than synthetic placeholder data
- You need a GUI or web interface for generating fake data
