Compiling and running

At the beginning of this chapter, we started an instance of the PostgreSQL database that we will use to check our tool. Compile the example we created with Cargo and print the available subcommands with the following command:

cargo run -- --helpYou will see the next output:USAGE:    users [OPTIONS] <SUBCOMMAND>FLAGS:    -h, --help       Prints help information    -V, --version    Prints version informationOPTIONS:    -d, --db <ADDR>    Sets an address of db connectionSUBCOMMANDS:    add       add user to the table    create    create users table    help      Prints this message or the help of the given subcommand(s)    list      print list of users
