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)); /// ``` #[derive(Clone)] pub struct HeaderMap<T = HeaderValue> { // Used to mask values to get an index mask: Size, indices: Box<[Pos]>, entries: Vec<Bucket<T>>, extra_values cursor: Option<Cursor> danger:Danger, } // # 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 // for this divergence are that `HeaderMap` is a multimap and the structure has // 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. // // [1]: https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing /// `HeaderMap` entry iterator. /// /// Yields `(&HeaderName, &value)` tuples.
