As I do frequently, I corrected for the latest clippy warnings. This will make sure the CI won't complain in the future. We could automate this btw and maybe run the nightly version of clippy.

//! Basic example for a AutoNAT server that supports the /libp2p/autonat/1.0.0 and "/ipfs/0.1.0" protocols.
|
|
//!
|
|
//! To start the server run:
|
|
//! ```sh
|
|
//! cargo run --example server -- --listen-port <port>
|
|
//! ```
|
|
//! The `listen-port` parameter is optional and allows to set a fixed port at which the local peer should listen.
