Hello World in Rust

This is a default hello world project written in rust. Future of bioinformatics?

The basics

First install rust. I am using rustup

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

Navigate to the parent directory of your coding projects and create the hello_world* project

cargo new hello_world

Notice that the project is conveniently set up with a hello world script.

Now we can build:

❯ cargo build
   Compiling hello_world v0.1.0 (/home/mattis/CodeZone/hello_world)
    Finished dev [unoptimized + debuginfo] target(s) in 0.11s

and run:

❯ cargo run
    Finished dev [unoptimized + debuginfo] target(s) in 0.00s
     Running `target/debug/hello_world`
Hello, world!

of course you can also run the executable directly after building:

❯ target/debug/hello_world
Hello, world!

* rust uses snake or kebab naming conventions, so hello_world and hello-world are accepted

Quality of life

Add cargo-edit:

cargo install cargo-edit

Now I will no longer have to edit the Cargo.toml directly, instead I add a crate like this:

cargo add clap

and voilá! dependencies are updated!
