Supported Types

Primitives: u8, u16, u32, u64, u128, i8-i128, bool
Solana: PublicKey, Signature
Complex: String, Vec<T>, Option<T>
Structs: With #[solana] and #[account] attributes
Enums: Unit, Tuple, and Struct variants

CLI Commands

lumos init - Initialize new project
lumos generate - Generate Rust + TypeScript code
lumos validate - Validate schema syntax
lumos check - Verify generated code is up-to-date

📊 Quality Metrics

✅ 64/64 tests passing (100% success rate)
✅ E2E tests with actual Rust compilation
✅ Zero clippy warnings
✅ Zero rustfmt violations
✅ Zero vulnerabilities (security audit clean)
✅ 5 real-world examples (Gaming, NFT, DeFi, DAO, Token Vesting)

🏗️ Architecture

LUMOS uses an Intermediate Representation (IR) architecture:

.lumos → Parser (syn) → AST → Transform → IR → Generators → .rs + .ts

This design makes it easy to add support for new target languages in the future (Python, C++, Go, etc.)
