 Take care of the order in which you apply extractors as some extractors
-mutate the request.
-
-For example using [`HeaderMap`] as an extractor will make the headers
-inaccessible for other extractors on the handler. If you need to extract
-individual headers _and_ a [`HeaderMap`] make sure to apply the extractor of
-individual headers first:
-
-```rust,no_run
-use axum::{
-    extract::TypedHeader,
-    routing::get,
-    headers::UserAgent,
-    http::header::HeaderMap,
-    Router,
-};
-
-async fn handler(
-    TypedHeader(user_agent): TypedHeader<UserAgent>,
-    all_headers: HeaderMap,
-) {
-    // ...
-}
-
-let app = Router::new().route("/", get(handler));
-# async {
-# axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap();
-# };
-```
-
-Extractors that consume the request body can also only be applied once as
-well as [`Request`], which consumes the entire request:
-
-```rust,no_run
-use axum::{
-    routing::get,
-    http::Request,
-    body::Body,
-    Router,
-};
-
-async fn handler(request: Request<Body>) {
-    // ...
-}
-
-let app = Router::new().route("/", get(handler));
-# async {
-# axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap();
-# };
-```
+mutate the request, such as consuming the request body, which can only be done
+once.
 
 Extractors always run in the order of the function parameters that is from
 left to right.
