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

# Install from crates.io
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

# 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:

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:

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

| TypeScript | Rust | | -------------- | -------------------- | | 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

interface Container<T> {
	value: T;
	getValue(): T;
	setValue(value: T): void;
}

pub trait Container<T> {
    fn get_value(&self) -> &T;
    fn set_value(&mut self, value: T);
}

Class to Struct Mapping

class Calculator {
	private result: number = 0;

	add(value: number): this {
		this.result += value;
		return this;
	}
}

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
    }
}
