Architecture

ArchCalc follows a clean separation of concerns, dividing responsibilities between a high-performance Rust backend and a reactive SolidJS frontend, connected via Tauri's IPC bridge.

Core Structure

Frontend (SolidJS)
        ↓
    Tauri IPC
        ↓
Backend (Rust)

Backend (Rust)

• Business Logic & Math Engine: Evaluates expressions using a custom tokenizer, parser, and AST evaluator.
• File Storage: Handles reading and writing user history securely to the local filesystem.
• System APIs: Uses native desktop features where necessary via Tauri APIs.

Frontend (SolidJS)

• UI & Interactions: Delivers a fast, reactive user interface for typing equations and viewing results.
• State Management: Maintains the application state efficiently.
• IPC Communication: Calls Rust functions asynchronously without blocking the UI thread.
