rustup update

You can rustup use x.y.z for a specific version or toolchain.

These are the files / directories that are created and/or modified with this install:

~/.config/envman/PATH.env
~/.cargo/
~/.rustup/
<PROJECT-DIR>/Cargo.toml
<PROJECT-DIR>/src/main.rs
<PROJECT-DIR>/src/lib.rs

Rust is what C++ and D were trying to do, but didn't. It's a modern, safe, high-performance language, which also just so happens to be used to build all of your favorite CLI tools, such as:

• rg (ripgrep, modern grep)
• fd (modern find)
• sd (modern sed)
• lsd (modern ls)
• bat (modern cat)

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

cargo install ripgrep

cargo new hello --bin
pushd ./hello/
cargo build --release
./target/release/hello
> "Hello, world!"
