I wanted to talk about basic types in Rust. Lets begin with Numerical Types in Rust, since Rust is a statically typed language, which means that it must know the types of all variables at compile time. I will talk about number types that are built into the language.

Numerical Types

Numerical values are divided into Integer Types and Floating-point type. A simple numerical type can be signed integer types or unsigned integer types.

Integer Data types are listed below:

let a = 100; // The default integer type in Rust is i32
let b: i8 = -128; //explicitly telling it will be an i8 type
let x = 2i8; // Equals to `let x: i8 = 2;` personally I don't like this way of, I prefer the previous statement rather

let a = 100;

Continuting on from where we left off, in this post I will refactor my code to use a function such that I can reuse my code later on. I will showcase how to write Functions in Rust with VSCode.

Intro

If we look at our previous post we have a very simple main function and it is just getting user input and then it outputs it with the println method. Its not one of the most elegant code but we we taking baby steps here. As a preview of our code code, it looks like below.

use std::io::stdin;
fn main() {
    let mut name = String::new();
    println!("Please enter your name &gt;");
    stdin().read_line(&amp;mut name).expect("Failed input");
    println!("Hello {}", name);
}

use std::io::stdin;

fn main() {

let
