Struct HeadersRef 

pub struct HeadersRef<'a> { /* private fields */ }

Zero-copy header reference.

Wraps a reference to a header map without cloning.

Implementations

impl<'a> HeadersRef<'a>

pub fn new(headers: &'a HashMap<String, Vec<String>>) -> Self

Create a new header reference.

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

Get a header value by name.

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

Get the first value for a header.

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

Check if a header exists.

pub fn len(&self) -> usize

Get the number of unique header names.

pub fn is_empty(&self) -> bool

Check if headers are empty.

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

Iterate over header names and values (no allocation).

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

Iterate over flattened header name-value pairs.

pub fn to_owned(&self) -> HashMap<String, Vec<String>>

Convert to owned HashMap (clones).

pub fn as_inner(&self) -> &HashMap<String, Vec<String>>

Get the underlying reference.
