TypeScript-Rust-Compiler - TypeScript to Rust Compiler

A high-performance compiler that transforms TypeScript code into idiomatic Rust, supporting all TypeScript features including advanced types, generics, decorators, and async/await patterns.

🚀 Features

• Complete TypeScript Support: All TypeScript features including advanced types, generics, decorators, and modules
• High Performance: Lightning-fast compilation with optimization support
• Type Safety: Full type safety preservation from TypeScript to Rust
• Runtime Support: Optional runtime for TypeScript semantics
• Project Support: Compile entire TypeScript projects to Rust projects
• Modern Rust: Generates idiomatic Rust code with latest features

📦 Installation

# 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

# Compile a single TypeScript file
typescript-rust-compiler input.ts -o output.rs

# Compile with optimization
typescript-rust-compiler input.ts -o output.rs --optimize

# Compile with runtime support
typescript-rust-compiler input.ts -o output.rs --runtime

# Compile an entire project
typescript-rust-compiler src/ -o rust-project/

Example

TypeScript Input:

interface User {
	name: string;
	age: number;
	email?: string;
}

class UserService {
	private users: User[] = [];

	addUser(user: User): void {
		this.users.push(user);
	}

	findUser(name: string): User | undefined {
		return this.users.find((u) => u.name === name);
	}

	getAllUsers(): User[] {
		return [...this.users];
	}
}

async function fetchUser(id: string): Promise<User> {
	// API call simulation
	return {
		name: 'John Doe',
		age: 30,
		email: 'john@example.com',
	};
}

Generated Rust Output:

use serde::{Deserialize, Serialize};
use std::collections::HashMap;

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct User {
    pub name: String,
    pub age: i32,
    pub email: Option<String>,
}

pub struct UserService {
    users: Vec<User>,
}

impl UserService {
    pub fn new() -> Self {
        Self { users: Vec::new() }
    }

    pub fn add_user(&mut self, user: User) {
        self.users.push(user);
    }

    pub fn find_user(&self, name: &str) -> Option<&User> {
        self.users.iter().find(|u| u.name == name)
    }

    pub fn get_all_users(&self) -> Vec<User> {
        self.users.clone()
    }
}

pub async fn fetch_user(id: &str) -> Result<User, Box<dyn std::error::Error>> {
    // API call simulation
    Ok(User {
        name: "John Doe".to_string(),
        age: 30,
        email: Some("john@example.com".to_string()),
    })
}

🔧 Advanced Features

Type Mapping

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
    }
}
