# Configures a server before running it

## Defaults

The default configuration is as follows:

* port: the contents of the `PORT` env var or else 8080
* host: the contents of the `HOST` env var or else "localhost"
* signals handling and graceful shutdown: enabled on cfg(unix) systems
* tcp nodelay: disabled
* tls acceptor: none

## Usage

```rust
let stopper = trillium_tokio::Stopper::new();
# stopper.stop(); // stoppping the server immediately for the test
trillium_tokio::config()
    .with_port(0)
    .with_host("127.0.0.1")
    .without_signals()
    .with_nodelay()
    .with_acceptor(()) // see [`trillium_rustls`] and [`trillium_native_tls`]
    .with_stopper(stopper)
    .run(|conn: trillium::Conn| async move {
        conn.ok("hello tokio")
