What is Cargo?

Cargo is Rust’s official build system and package manager. It handles:

- Creating new projects with a standard structure
- Building your code (uses rustc under the hood)
- Downloading and managing dependencies (called crates) from https://crates.io
- Running tests, benchmarks, and generating documentation
- Packaging your project for distribution

Project metadata lives in a Cargo.toml file (similar to package.json in Node.js or pom.xml in Maven). Cargo ensures builds are *repeatable*, *reliable*, and easy to share.

Steps to Create Your First Rust Project

1️⃣ Open a terminal

- PowerShell on Windows
- Terminal on macOS or Linux

2️⃣ Create a directory for our Rust journey

mkdir RustJourney
cd RustJourney

3️⃣ Create a new project using Cargo

cargo new hello_world
cd hello_world

Cargo generates this structure:

- src/main.rs → main source file
- Cargo.toml → project configuration
- .gitignore → Git ignore rules



4️⃣ Open src/main.rs

Cargo pre-fills it with:

fn main() {
    println!("Hello, world!");
}

Explanation:

- fn main() → entry point of every Rust executable
- println! → a macro (note the !) that prints to the console
- ; ends statements (Rust is strict)
- 4 spaces indentation is the convention



5️⃣ Build and run the project

cargo run

Output:

Hello, world!

Build without running:

cargo build

Optimized release build:

cargo build --release

Congrats! You’ve completed your first Rust project.

If you see errors, don’t panic—Rust’s compiler messages are very helpful.

Summary

- Installed Rust using rustup
- Learned what Cargo is
- Created a Hello World project
- Ran Rust code with cargo run

Practice: Change "Hello, world!" to print your name.

2025 was an amazing year

This shit is getting out of hand

First safaricom now tele

መሄጃ የላቸውም ብለው መጫወቻ አረጉን😭

If I’m not back in five minutes, just wait longer.

Really impressed by the work @andymarrow put into this project.

The development is clean and intentional, and the problem-solving behind it is clearly thought through. Projects like this don’t come together without a lot of iteration and dedication.

Just 9 people and we will hit 600 before / on the new year's
Welp @eyu_terminal

#newchallenge

what if i could hit 100 subs before 2026

0ne to go to hit 40 before 2026, let's go comrades 🫡
Yitu's Pixverse

Finally 100 subs before 2026🔥🔥

Thanks fam

I wonder if we could hit 500 subscribers before 2026🤔

Happy new year fam

Imagine it logging with pdf

Just built a side project

> It is simple cli tool for download manager
> You can download the link from many sites
> I published it into the python library so many user can access it by installing the package
> to install the tool use the instruction provided in the github or pypi
here is the link - https://pypi.org/project/ultradl-pro/
and
https://github.com/Dawaman43/ultradl-pro

it is beta version

i will improve it a lot so test it if you want to download stuffs


> I know i built fastdl first but the cons of fastdl is it only work in linux and firefox
> But ultraldl is cross platform tool so go play with it

BTW you need python to install the tool

To start the cli too u can run

utradl
or
ultradl-pro

🤞 it will hopefully force sonnet to be chipper though z.ai already have bigger open model called GLM-4.7 with way chipper api price & nice performance am shore knowing anyone can host this smaller model in smaller v-ram and become a compotator is good motivation to keep price low and work on sonnet 5 🙄

They should open code red else they are coping. 😁
