Cargo

Cargo is the Rust build and pacakage management system. A package is called a Crate (like an npm module or .net nuget).

• To create a new project crate:

  • cargo new mycrate
  • cd mycrate
  • git init .
  • hub new (hub is deprecated, github now has a gh command)

• To upgrade all your your existing crates you have installed run cargo install-update -a

Say you have an existing directory, an empty git repo.
To turn this into a Rust project you run:

cargo init . --bin

If you then execute cargo run it will compile and run it, printing out Hello World!

Cargo Add-ons

cargo install cargo-edit this allows you to cargo add/rm <crate> and cargo upgrade --dry-run
