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/get/1
```
```
{"name":"user1","registration_date":"2020-05-09T06:17:26"}
```
```
curl -X GET http://localhost:7800/api/users/get
```
```
[{"name":"user1","registration_date":"2020-05-09T06:17:26"},{"name":"user2","registration_date":"2020-05-12T12:43:13"},{"name":"user3","registration_date":"2020-05-15T07:47:50"}]
```
### Create User
```
curl -H "content-type: application/json" -X POST http://localhost:7800/do_registration --data '{"name":"user4","password":"test"}'
```
```
[{"name":"user1","registration_date":"2020-05-09T06:17:26"},{"name":"user2","registration_date":"2020-05-12T12:43:13"},{"name":"user3","registration_date":"2020-05-15T07:47:50"},{"name":"user4","registration_date":"2020-08-01T05:04:05"}]
```
### DTO Validation
```
curl -H "content-type: application/json" -X POST http://localhost:7800/do_registration --data '{"name":"abc","password":"test"}'
```
```
ValidationErrors({"name": Field([ValidationError { code: "length", message: None, params: {"value": String("abc"), "min": Number(4), "max": Number(10)} }])})
```
## Memory Usage
Memory usage as compared to interpreted language was my primary motivation for looking into rust as a backend language. As of writing, the demo app uses only 1.3MB of memory.
