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
