A CRUD Server

In this lesson, we’ll learn how to create a simple CRUD server and structure a Rust project.

Once again, we’ll work on a simple employee management system as our test project.

A plan of action

A CRUD server needs at least four different routes to create, read, update, and delete records. Many CRUD servers also include a route to get all the records that are present.

These are the basic routes we’ll need:

Method	Route	Function
GET	/employees	Get all records
GET	/employee/<id>	Get a single record
POST	/employee	Create a record
PUT	/employee/<id>	Update a record
DELETE	/employee/<id>	Delete a record

In this simple example, we don’t need to deal with data storage, as the focus will be on serving data. So we’ll use a simple in-memory solution.

Source filesystem

We’ll distribute the code over different source files, each of which will be treated as a different Rust mod. Because of this, our project’s structure will resemble the structure of a node.js or express project. This structure is very common, time-tested, and intuitive.
