Struct Headers 

pub struct Headers { /* private fields */ }

Implementations

impl Headers

pub fn new() -> Self

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

Replace any existing values for this name.

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

Add a value, keeping the ones already present. Used for Set-Cookie, which is the one header that legitimately repeats.

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

pub fn get_all(&self, name: &str) -> &[String]

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

pub fn remove(&mut self, name: &str)

pub fn is_empty(&self) -> bool

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

Iterate every (name, value) pair, repeated headers included.

pub fn content_length(&self) -> Option<usize>

The parsed Content-Length, when present and well-formed.

pub fn content_type(&self) -> Option<&str>

The media type without parameters: application/json; charset=utf-8 → application/json.
