## compiling
Compiling is a little strange.
The SQL-statements are checked for correctness at compile-time, unfortunately this means that the
database needs to be running at compile-time too.
```sh
docker build -t datatrash .
docker cp datatrash:/home/rust/.cargo/bin/datatrash datatrash
```
To get set up:
or, to just run it in docker
- Start a postgresql somewhere
- Set its connection url in the `.env` file
- Run the `init-db.sql` script in the database (`cat init-db.sql | psql`)
- Build the project `cargo build --release`
```sh
docker-compose up -d --build
```
