RustC – Rust Compiler Android App

**RustC** is an advanced **Android compiler application** built for **Rust**, providing a dynamic environment for writing, compiling, and analyzing Rust code directly on your mobile device. It features a robust backend that exposes compiler internals like **token streams**, **Abstract Syntax Trees (AST)**, **symbol tables**, and **Control Flow Graphs (CFG)**.

✨ Key Features & Compiler Insights

Real-time Rust Compilation

Compile and execute **Rust code** on a powerful backend, receiving immediate feedback and error messages.

Code Editor & Syntax Highlighting

Offers a feature-rich code editor with **syntax highlighting** for Rust, ensuring a comfortable coding experience.

Token Stream Visualization

Visualize the raw **token stream** generated by the Rust compiler, aiding in understanding the lexical analysis phase.

AST & CFG Exploration

Explore the **Abstract Syntax Tree (AST)** and **Control Flow Graph (CFG)** of your Rust code via intuitive tree renderers and graph views.

Symbol Table & LLVM IR Viewing

Inspect the **symbol table** and generated **LLVM IR** to gain deeper insights into Rust's compilation process.

State Persistence

Utilizes **Jetpack DataStore** to persist your last edited code snippet and language preferences locally.

// Rust Example: Hello World with a function
fn main() {
    let message = "Hello from RustC!";
    println!("{}", message);
}

// LLVM IR snippet for a simple integer addition
%add.result = add i32 10, 20
