Rust

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

Example

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.

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

To update the toolchain, try rustup update.
