RUST Calculator API

This API was created for studying purposes. I was interested in learning Rust and started with a simple server to put into practice basic concepts that I learned. The primary goal was to understand how to structure a web service using Rust.

http

GET http://127.0.0.1:8080/

Calculator Operations

All calculator endpoints accept POST requests with a JSON body: json

{
"a": 5,
"b": 5
}

Available endpoints:

• POST /calculator/add - Performs addition
• POST /calculator/sub - Performs subtraction
• POST /calculator/mul - Performs multiplication
• POST /calculator/div - Performs division
• POST /calculator/pow - Performs power operation

Project Structure

src/
├── main.rs # Application entry point
├── routes.rs # Route configurations
└── calculator/
└── mod.rs # Calculator logic

Running the Project

1. Clone the repository
2. Use Cargo to build and run the project:

bash

cargo run

3. The server will start at http://127.0.0.1:8080

Learning Notes

• Actix Scopes: Help organize routes logically, such as grouping calculator endpoints
• Serde Magic: Automatically converts between Rust structs and JSON
• Handler Pattern: Each endpoint has a dedicated async handler function
• Type Safety: Rust's type system ensures correct data handling

May the Rust be with you! 🦀✨

Remember: Just as a Jedi builds their lightsaber, we build our APIs with precision, care, and proper error handling!
