//! Raw request body access for HTTP requests.
//!
//! This module provides the [`Bytes`](crate::extractors::bytes::Bytes) extractor for accessing the raw HTTP request body
//! as a `hyper::body::Incoming` stream. This is useful when you need low-level access
//! to the request body stream for custom processing, streaming, or when working directly
//! with hyper's body types.
//!
//! # Examples
//!
//! ```rust
//! use tako::extractors::bytes::Bytes;
//! use tako::types::Request;
//! use http_body_util::BodyExt;
//!
//! async fn handle_raw_body(Bytes(body): Bytes<'_>) {
//!     // Access the raw hyper body stream
//!     println!("Got access to raw body stream");
//!
//!     // You can use hyper's body utilities to read the body
//!     // let full_body = body.collect().await.unwrap();
//!     // let bytes = full_body.to_bytes();
//! }
//! ```
