Testing out the Rust framework Actix-Web to create a JSON API CRUD Web App.

API Demo

Get Users

curl -X GET http://localhost:7800/api/users

{
  "username": "user1",
  "registration_date": "2020-05-09T06:17:26"
}

curl -X GET http://localhost:7800/api/users

[
  {
    "username": "user1",
    "registration_date": "2020-05-09T06:17:26"
  },
  {
    "username": "user2",
    "registration_date": "2020-05-12T12:43:13"
  },
  {
    "username": "user3",
    "registration_date": "2020-05-15T07:47:50"
  }
]

Create User

curl -H "content-type: application/json" \
-X PUT \
-i http://localhost:7800/api/users \
--data '{"username":"user4","password":"test"}'

[
  {
    "username": "user1",
    "registration_date": "2020-05-09T06:17:26"
  },
  {
    "username": "user2",
    "registration_date": "2020-05-12T12:43:13"
  },
  {
    "username": "user3",
    "registration_date": "2020-05-15T07:47:50"
  },
  {
    "username": "user4",
    "registration_date": "2020-08-01T05:04:05"
  }
]

Memory Usage

Memory usage as compared to interpreted languages was my primary motivation for looking into rust as a backend language. As of writing, the demo app uses less than 50MB of memory.
