Learning the Rust programming language

This repository is dedicated to exploring and practicing Rust through small projects.

📌 Project 1: Calculator

The first project is a simple calculator.
It consists of three main stages:

1. Tokenization — the calculator parses a math expression into tokens (numbers, operators, brackets, etc.).
2. Math expession parse - Analyzes and transform a sequence of tokens.
3. Conversion to Reverse Polish Notation (RPN) — using the Shunting Yard algorithm.
4. Evaluation — the calculator evaluates the expression in RPN form.

✅ Features:

• Supports basic operators: +, -, *, /
• Handles parentheses
• Parses floating-point numbers

✍️ Example:

let expression = "(12.5 + 3) * 2";
let result = calculator::evaluate(expression).unwrap();
println!("Result: {}", result); // Output: 31.0
