I have no experience with Rust language at all. So when I try Rust, maybe something I don't understand at the moment I write this. But I want to give it a try!

🌱 Getting started

After installing Rush language based on your using OS. To verify the successful installation:

rustc --version
# output: rustc 1.67.0 (fc594f156 2023-01-24)
cargo --version
# output: cargo 1.67.0 (8ecd4f20a 2023-01-10)

🍏 Generating a new project

cargo new hello-rust
cd hello-rust
ls
code .

Next, we need to prepare the development environment. For VSCode, I'm using Rust analyzer extension. Other extensions:

• even-better-toml - Syntax highlighting and validation for TOML documents (Cargo.toml)

cargo run

Output:

• Compiling - hello-rust v0.1.0 (path\to\hello-rust)

• Finished - dev [unoptimized + debuginfo] target(s) in 0.71s

• Running - target\debug\hello-rust.exe

cargo build

Output:

• Finished dev [unoptimized + debuginfo] target(s) in 0.00s

cargo test

Output:

• Compiling hello-rust v0.1.0 (path\to\hello-rust)

• Finished test [unoptimized + debuginfo] target(s) in 0.32s

• Running unittests src\main.rs (target\debug\deps\hello_rust-e2e48f3e969733ad.exe)

🌽 Source code

Cargo.toml:

[package]
name = "hello-rust"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]

Cargo.lock :

# This file is automatically @generated by Cargo.
# It is not intended for manual editing.
version = 3

[[package]]
name = "hello-rust"
version = "0.1.0"

.gitignore :

/target

src\main.rs :

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

Let's view deeper in ignored folder:

tree .

My running OS is Windows, so the output is:

I think I need to rest now, too many things to learn!
