# TypeScript-Rust-Compiler
A TypeScript to Rust compiler that transforms TypeScript code into idiomatic, efficient Rust code with growing TypeScript feature support.

## 🎯 Overview
This project aims to create a high-performance compiler that can translate TypeScript code into safe, efficient Rust code while preserving TypeScript's type system and semantics.
## 🚀 Current Features
### ✅ **Fully Working**
- **Variables**: `let`, `const`, `var` with type annotations
- **Primitive Types**: `string`, `number`, `boolean`, `null`, `undefined`
- **Arrays**: `number[]`, `Array<string>`, readonly arrays
- **Objects**: Object literals with type annotations
- **Functions**: Function declarations with parameters and return types
- **Classes**: Basic class declarations with properties and methods
- **Interfaces**: Interface definitions (generate Rust traits)
- **Enums**: Basic enums and string enums with const generation
- **Type Aliases**: Simple type alias declarations
### ⚠️ **Partially Working**
- **Complex Types**: Union and intersection types (basic support)
- **Generic Types**: Basic generic type handling
- **Export Statements**: `export` declarations are parsed
- **Advanced Expressions**: Template literals, optional chaining
### ❌ **Not Yet Implemented**
- **Import/Export Resolution**: Import statements are parsed but not fully resolved
- **Class Inheritance**: `extends` and `implements` clauses need more work
- **Advanced Type System**: Mapped types, conditional types, template literal types
- **Module System**: Full module resolution and linking
- **Decorators**: Decorator syntax and processing
- **Namespaces**: Namespace declarations and scoping
## 📦 Installation
```bash
# Install from crates.io (when published)
cargo install TypeScript-Rust-Compiler
# Or build from source
git clone https://github.com/FrankFMY/TypeScript-Rust-Compiler.git
cd TypeScript-Rust-Compiler
cargo build --release
```
## 🎯 Quick Start
### Basic Usage
```bash
# Compile a single TypeScript file
cargo run -- --input input.ts --output output.rs
# Compile with optimization
cargo run -- --input input.ts --output output.rs --optimize
# Compile with runtime support
cargo run -- --input input.ts --output output.rs --runtime
# Compile an entire project
cargo run -- --input src/ --output rust-project/
# Enable debug mode for detailed output
cargo run -- --input input.ts --output output.rs --debug
```
### Example
**TypeScript Input:**
```typescript
interface User {
name: string;
age: number;
}
class Person {
name: string;
age: number;
constructor(name: string, age: number) {
this.name = name;
this.age = age;
}
greet(): string {
return `Hello, I'm ${this.name}`;
}
}
function add(a: number, b: number): number {
return a + b;
}
const result = add(5, 3);
```
**Generated Rust Output:**
```rust
use serde::{Deserialize, Serialize};
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Person {
pub name: String,
pub age: f64,
}
impl Person {
pub fn new(name: String, age: f64) -> Self {
Self { name, age }
}
pub fn greet(&self) -> String {
format!("Hello, I'm {}", self.name)
}
}
pub fn add(a: f64, b: f64) -> f64 {
(a + b)
}
let result: f64 = add(5.0, 3.0);
```
## 🔧 Advanced Features
### Type Mapping
| `string` | `String` |
| `number` | `f64` |
| `boolean` | `bool` |
| `any` | `Box<dyn Any>` |
| `unknown` | `Box<dyn Any>` |
| `void` | `()` |
| `never` | `!` |
| `Array<T>` | `Vec<T>` |
| `Promise<T>` | `Future<Output = T>` |
| `Record<K, V>` | `HashMap<K, V>` |
### Generic Support
```typescript
interface Container<T> {
value: T;
getValue(): T;
setValue(value: T): void;
}
```
```rust
pub trait Container<T> {
fn get_value(&self) -> &T;
fn set_value(&mut self, value: T);
}
```
### Class to Struct Mapping
```typescript
class Calculator {
private result: number = 0;
add(value: number): this {
this.result += value;
return this;
}
}
```
```rust
pub struct Calculator {
result: f64,
}
impl Calculator {
pub fn new() -> Self {
Self { result: 0.0 }
}
pub fn add(mut self, value: f64) -> Self {
self.result += value;
self
}
}
```
