Hands-On Microservices with Rust

Declaring the data structure

Our tool will have two modules with a data structure. The first is the src/schema.rs module, which contains a table! macro call that declares the fields of every table. In our case, this module contains the following declaration:

table! {    users (id) {        id -> Text,        name -> Text,        email -> Text,    }}

This file was automatically generated by the diesel setup command. When you run a setup, it creates a diesel.toml configuration file with the following contents:

# For documentation on how to configure this file,# see diesel.rs/guides/configuring-diesel-cli[print_schema]file = "src/schema.rs"

As you can see, the config has a schema module reference. A schema.rs file is also generated, and will be updated on every compilation. ...
