/// A specialized [multimap](<https://en.wikipedia.org/wiki/Multimap>) for
/// header names and values.
///
/// # Overview
///
/// `HeaderMap` is designed specifically for efficient manipulation of HTTP
/// headers. It supports multiple values per header name and provides
/// specialized APIs for insertion, retrieval, and iteration.
///
/// The internal implementation is optimized for common usage patterns in HTTP,
/// and may change across versions. For example, the current implementation uses
/// [Robin Hood
/// hashing](<https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing>) to
/// store entries compactly and enable high load factors with good performance.
/// However, the collision resolution strategy and storage mechanism are not
/// part of the public API and may be altered in future releases.
///
/// # Iteration order
///
/// Unless otherwise specified, the order in which items are returned by
/// iterators from `HeaderMap` methods is arbitrary; there is no guaranteed
/// ordering among the elements yielded by such an iterator. Changes to the
/// iteration order are not considered breaking changes, so users must not rely
/// on any incidental order produced by such an iterator. However, for a given
/// crate version, the iteration order will be consistent across all platforms.
///
/// # Adaptive hashing
///
/// `HeaderMap` uses an adaptive strategy for hashing to maintain fast lookups
/// while resisting hash collision attacks. The default hash function
/// prioritizes performance. In scenarios where high collision rates are
/// detected—typically indicative of denial-of-service attacks—the
/// implementation switches to a more secure, collision-resistant hash function.
///
/// # Limitations
///
/// A `HeaderMap` can store at most 32,768 entries \(header name/value pairs\).
/// Attempting to exceed this limit will result in a panic.
///
/// [`HeaderName`]: struct.HeaderName.html
/// [`HeaderMap`]: struct.HeaderMap.html
///
/// # Examples
///
/// Basic usage
///
/// ```
/// # use http::HeaderMap;
/// # use http::header::{CONTENT_LENGTH, HOST, LOCATION};
/// let mut headers = HeaderMap::new();
///
/// headers.insert(HOST, "example.com".parse().unwrap());
/// headers.insert(CONTENT_LENGTH, "123".parse().unwrap());
///
/// assert!(headers.contains_key(HOST));
/// assert!(!headers.contains_key(LOCATION));
///
/// assert_eq!(headers[HOST], "example.com");
///
/// headers.remove(HOST);
///
/// assert!(!headers.contains_key(HOST));

// # Implementation notes
//
// Below, you will find a fairly large amount of code. Most of this is to
// provide the necessary functions to efficiently manipulate the header
// multimap. The core hashing table is based on robin hood hashing [1]. While
// this is the same hashing algorithm used as part of Rust's `HashMap` in
// stdlib, many implementation details are different. The two primary reasons
/// `HeaderMap` is designed specifically for efficient manipulation of HTTP
// been optimized to take advantage of the characteristics of HTTP headers.
//
// ## Structure Layout
//
// Most of the data contained by `HeaderMap` is *not* stored in the hash table.
// Instead, pairs of header name and *first* associated header value are stored
// in the `entries` vector. If the header name has more than one associated
// header value, then additional values are stored in `extra_values`. The actual
// hash table (`indices`) only maps hash codes to indices in `entries`. This
// means that, when an eviction happens, the actual header name and value stay
// put and only a tiny amount of memory has to be copied.
//
// Extra values associated with a header name are tracked using a linked list.
// Links are formed with offsets into `extra_values` and not pointers.
//
