The Rust programming language is syntactically similar to C++ and is designed for performance and safety, especially safe concurrency.

Installation

The usual assumption is that you need to install rust in order to use or compile rust. However, you must install rustc in order to compile programs written in Rust.

aptitude install rustc

For Debian 10 Buster the dependencies are:

cargo gdb libbabeltrace-ctf1 libbabeltrace1 libc6-dbg libdw1 libhttp-parser2.1
libllvm7 libstd-rust-1.34 libstd-rust-dev rust-gdb

For Debian 11 Bullseye the dependencies are:

cargo gdb libbabeltrace1 libc6-dbg libdebuginfod1 libsource-highlight-common
libsource-highlight4v5 libstd-rust-1.48 libstd-rust-dev rust-gdb

Hello World

The famous source code for ‘Hello World!’ in Rust is:

echo 'fn main() {' > hello-world.rs
echo '    println!("Hello World!");' >> hello-world.rs
echo '}' >> hello-world.rs

This will give the file hello-world.rs with the content

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

Compiling

rustc hello-world.rs

Executing

./hello-world
Hello World!
