Hands-On Microservices with Rust

Adding a user subcommand implementation

The first subcommand of our users management tool is add. This command extracts the NAME and EMAIL of the user from the arguments and generates a new user identifier using the uuid crate. We will use this type across all our microservices. Look at the following code:

(CMD_ADD, Some(matches)) => {    let conn = pool.get()?;    let name = matches.value_of("NAME").unwrap();    let email = matches.value_of("EMAIL").unwrap();    let uuid = format!("{}", uuid::Uuid::new_v4());    let new_user = models::NewUser {        id: &uuid,        name: &name,        email: &email,    };    diesel::insert_into(schema::users::table)        .values(&new_user)        .execute(&conn)?;}

After we have extracted all the parameters, we create a NewUser instance from the models ...
