This web server is a very basic implementation of a REST API server built on top of the Rocket web framework using Rust, where the user can add, delete and get items from a To-Do list.

• Installing rust
• Rocket
• rusqlite
• Rust

• Recommended extension to install that watching and auto-reloading of the application through the use of cargo watch:

  cargo install cargo-watch

• Rust Analyzer

• To compile for development:

  cargo build

  This creates a binary in the target/debug/rest_api-rocket-rust directory.

• If cargo-watch is installed, then the following command can be used to compile and start the server:

  cargo watch -x run

  which will create the corresponding binary in target/release:

  target/release/rest_api-rocket-rust

  This will create a file data.sqlite in the root directory of the project.
  The server will, by default, start an HTTP API server on port 8000 and will only be accessible as localhost.

• To send a request to the server, use the following command in your terminal after starting the server:

  curl localhost:8000

  This will return the following response:

  {
    "message": "Hello, world!"
  }

  curl localhost:8000/todo

  This will return the following response:

  {
    "items": []
  }

  This will empty for the first time, since we have not added any items to the list yet.

• To add an item to the list, use the following command:

  curl localhost:8000/todo -X POST -d '"Item number 1"' -H "Content-Type: application/json"

  This will return the following response:

  {
    "message": "1 rows inserted"
  }

• To get the list of items, use the following command:

  curl localhost:8000/todo

  This will return the following response:

  {
    "items": [
      {
        "id": 1,
        "item": "Item number 1"
      }
    ]
  }

• To delete an item from the list, use the following command by specifying the id of the item:

  curl localhost:8000/todo/1 -X DELETE

  This will return the following response:

  {
    "message": "1 rows deleted"
  }
