Struct Headers 

pub struct Headers { /* private fields */ }

HTTP headers collection.

Implementations

impl Headers

pub fn new() -> Self

Create empty headers.

pub fn get(&self, name: &str) -> Option<&[u8]>

Get a header value by name (case-insensitive).

pub fn contains(&self, name: &str) -> bool

Returns true if a header is present (case-insensitive).

pub fn insert(&mut self, name: impl Into<String>, value: impl Into<Vec<u8>>)

Insert a header.

pub fn insert_from_slice(&mut self, name: &str, value: &[u8])

Insert a header from borrowed name/value slices.

This is a convenience for parsers that already have &str/&[u8] and want to avoid constructing intermediate owned buffers.

pub fn remove(&mut self, name: &str) -> Option<Vec<u8>>

Remove a header value by name (case-insensitive).

pub fn iter(&self) -> impl Iterator<Item = (&str, &[u8])>

Iterate over all headers as (name, value) pairs.

pub fn len(&self) -> usize

Returns the number of headers.

pub fn is_empty(&self) -> bool

Returns true if there are no headers.

Trait Implementations

impl Debug for Headers

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

Formats the value using the given formatter.

impl Default for Headers

fn default() -> Headers
