Rust

The Rust programming language is a compiled, static-typed language built on top of the LLVM project.

Example

A hello world program looks like:

fn main() {
    println!("Hello World!");
}

To compile and run the program, try:

rustc hello.rs
./hello

It is more common to use cargo(1), which wraps rustc(1). It depends on the project following a standard file structure, and on being in the project's root directory.

cargo build --release
./hello
# or
cargo run

The release flag enables all optimizations. These optimizations are also accessible with rustc(1), but through multiple flags and options.

Installation

The only supported method for installing and maintaining the Rust toolchain is through rustup.

To get started, run:

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

Once rustup is installed, try rustup update to update the toolchain.
