`rocket-no-content` provides a singular struct `EmptyResponse` which has a Responder implementation that returns "204 No Content". In addition to this, it also implements a schema for okapi.
I got tired of copying the same struct and implementation between projects, so here it is.
```rust
use rocket-no-content::EmptyResponse;
pub async fn test() -> EmptyResponse {
EmptyResponse
// Responds with "204 No Content"
}
```
