Hands-On Microservices with Rust

Adding dependencies

Let's create a new project with all the necessary dependencies. We will create a binary utility for managing users in a database. Create a new binary crate:

cargo new --bin users

Next, add the dependencies:

cargo add clap postgres

But wait! Cargo doesn't contain an add command. I've installed cargo-edit tool for managing dependencies. You can do this with the following command:

cargo install cargo-edit

You can also add dependencies manually by editing the Cargo.toml file, but as we are going to create more complex projects, the cargo-edit
