Rust

Variables

In Python, the variables are assigned with the type based on the content.

string_variable = 'some text'
int_variable = 33
print(type(string_variable), type(int_variable))

And, these variables are allowed to change in a program.

In Rust, the variables can either be mutable or immutable. By default, the variables are immutable.

Mutable - Values are allowed to change Immutable - Values are not allowed to change

fn main() {
let default_variable = 2;
println!("The value in default_variable is {}",{default_variable});

default_variable = 3;
//Here, the code will fail.
//Because we tried to modify the immutable variable

println!("The new value in default_variable is {}",{default_variable});

}

This is where Shadowing comes into picture.

What is rustup, rustc & rustdoc ?

rustup- Used to update the latest Rust version. rustc filename.rs - Used to compile rust source code. rustdoc - Rust documentation is generated from this command. This can generate documentation from markdown files. Also, it show the Rustbook opens in browser when called as rustup docs

Project initialization After installing Rust, we should initialize a project using Cargo cargo init project_path - This will create a project folder of below file structure.

Podcasts. That’s how I got introduced to the Rust language.

In one of the PythonBytes episode I heard about the PyOxidizer for the first time. Basically, it uses Rust to bundle Python code into an executable code. There is already quite a number of modules to convert code into an executable file. According to Michael Kennedy, the Git repo is so active, that made me to explore what the PyOxidizer is made of. Surprise, Surprise! Its made an amalgamation of Rust and Python, in 80-20 ratio.
