# Crate features

* **axum** -
  Enables the [`axum`] integration. Trace and metrics will contain the
  `http.route` attribute, populated with the path in the router that matches
  the request, as well as the `client.address` and `client.port` attributes.

* **reqwest_013** -
  Enables support for [`reqwest`] v0.13. Services [`trace::Http`] and [`metrics::Http`] can be
  used with `reqwest::Client`. Applying a server side service results in a panic.

[`reqwest`]: https://docs.rs/reqwest
