Struct HeaderMap 

pub struct HeaderMap { /* private fields */ }

EN: Case-insensitive HTTP headers retained for diagnostics and request construction. 中文：用于诊断和构造请求的大小写不敏感 HTTP 头集合。

Implementations

impl HeaderMap

pub fn new() -> Self

EN: Creates an empty header map. 中文：创建空的请求头集合。

pub fn from_pairs<I, P>(pairs: I) -> Self

where I: IntoIterator<Item = P>, P: IntoHeaderPair,

EN: Creates headers from name/value pairs. 中文：通过名称和值的键值对创建请求头集合。

pub fn insert(&mut self, name: impl Into<String>, value: impl Into<String>)

EN: Inserts or replaces a header value using ASCII case-insensitive header names. 中文：使用 ASCII 大小写不敏感的头名称插入或替换请求头。

pub fn get(&self, name: &str) -> Option<&str>

EN: Returns a header value by ASCII case-insensitive name. 中文：按 ASCII 大小写不敏感名称返回请求头值。

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

EN: Iterates over header names and values. 中文：遍历请求头名称和值。

Trait Implementations

impl Clone for HeaderMap

fn clone(&self) -> HeaderMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeaderMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HeaderMap

fn default() -> HeaderMap

Returns the “default value” for a type.

impl Eq for HeaderMap

impl<const N: usize> From<[(&str, &str); N]> for HeaderMap

fn from(value: [(&str, &str); N]) -> Self

Converts to this type from the input type.

impl PartialEq for HeaderMap

fn eq(&self, other: &HeaderMap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
