mod.rs HTTP header types The module provides [`HeaderName`], [`HeaderMap`], and a number of types used for interacting with `HeaderMap`. These types allow representing both HTTP/1 and HTTP/2 headers. # `HeaderName` The `HeaderName` type represents both standard header names as well as custom header names. The type handles the case insensitive nature of header names and is used as the key portion of `HeaderMap`. Header names are normalized to lower case. In other words, when creating a `HeaderName` with a string, even if upper case characters are included, when getting a string representation of the `HeaderName`, it will be all lower case. This allows for faster `HeaderMap` comparison operations. The internal representation is optimized to efficiently handle the cases most commonly encountered when working with HTTP. Standard header names are special cased and are represented internally as an enum. Short custom headers will be stored directly in the `HeaderName` struct and will not incur any allocation overhead, however longer strings will require an allocation for storage. ## Limitations `HeaderName` has a max length of 32,768 for header names. Attempting to parse longer names will result in a panic. # `HeaderMap` The [`HeaderMap`] type is a specialized [multimap](<https://en.wikipedia.org/wiki/Multimap>) structure for storing header names and values. It 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.
