-/// Server Core Struct
+/// Oblivion Server
+///
+/// Oblivion uses the `tokio` library to handle TCP connections. The `Server` struct
+/// is responsible for creating and managing the TCP listener and handling incoming
+/// connections. The `handle` function is called for each incoming connection,
+/// which creates a new `Session` and handles the incoming data. The `Router`
+/// is used to determine which handler function to call based on the incoming
+/// request.
+///
+/// # Example
+///
+/// ```rust
+/// # use oblivion::models::server::Server;
+/// # use oblivion::models::router::Router;
+/// # use anyhow::Result;
+/// # async fn runner() -> Result<()> {
+/// let router = Router::new(); // Create an empty router
+/// // Create an oblivion server and bind it to 127.0.0.1:8080
+/// let server = Server::new("127.0.0.1", 0, router);
+/// server.run().await;
+/// # Ok(())
+/// # }

+/// # async fn main() {
