This example illustrates

tokio_postgres
use of tokio_pg_mapper for postgres data mapping
deadpool_postgres for connection pooling
dotenv + config for configuration

Instructions

Create database user
```
createuser -P test_user
```
Enter a password of your choice. The following instructions assume you used testing as password.

This step is optional and you can also use an existing database user for that. Just make sure to replace test_user by the database user of your choice in the following steps and change the .env file containing the configuration accordingly.
Create database
```
createdb -O test_user testing_db
```
Initialize database
```
psql -f sql/schema.sql testing_db
```
This step can be repeated and clears the database as it drops and recreates the schema testing which is used within the database.

Create .env file:

SERVER_ADDR=127.0.0.1:8080
PG.USER=test_user
PG.PASSWD=testing
PG.HOST=127.0.0.1
PG.PORT=5432
PG.DBNAME=testing_db
PG.POOL.MAX_SIZE=16

Run the server:
```
cargo run
```

Using a different terminal send an HTTP POST request to the running server:

echo '{"email": "ferris@thecrab.com", "first_name": "ferris", "last_name": "crab", "username": "ferreal"}' | http -f --json --print h POST http://127.0.0.1:8080/users

...or using curl...

curl -d '{"email": "ferris@thecrab.com", "first_name": "ferris", "last_name": "crab", "username": "ferreal"}' -H 'Content-Type: application/json' http://127.0.0.1:8080/users

A unique constraint exists for username, so sending this request twice will return an internal server error (HTTP 500).
