01 Install Rust

Goal

Set up a complete Rust development environment with rustup, cargo, and rust-analyzer.

Steps

1. Install rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Follow the prompts (default is fine). This installs:

• rustc - the compiler
• cargo - package manager and build tool
• rustup - toolchain manager

2. Configure Shell

source ~/.cargo/env

Verify:

rustc --version
cargo --version
rustup --version

3. Install Components

rustup component add rust-analyzer rust-src rustfmt clippy

4. Update Toolchain

rustup update

Checkpoint

Run:

cargo new hello
cd hello
cargo run

Expected output:

   Compiling hello v0.1.0 (...)
    Finished dev [unoptimized + debuginfo] target(s) in 0.5s
     Running `target/debug/hello`
Hello, world!
