Struct Headers

pub struct Headers { /* private fields */ }

The HTTP header map. All the names are not case sensitive.

Example

let mut headers = mini_async_http::Headers::new();

assert!(headers.get_header("missing").is_none());

headers.set_header("Content-type","text/plain");
assert_eq!(headers.get_header("content-type").unwrap(),"text/plain");

headers.set_header("Content-type","application/json");
assert_eq!(headers.get_header("content-type").unwrap(),"application/json");

Implementations

impl Headers

pub fn new() -> Headers

Init an empty header struct

pub fn set_header(&mut self, name: &str, value: &str)

Set the given header name to the given value. If the key already exists overwrite the value.

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

Retrieve the value at the given key

pub fn iter(&self) -> HeaderIterator<'_>

Return an iterator over all the headers. All keys are lowercase

Trait Implementations

impl Clone for Headers

fn clone(&self) -> Headers

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Headers

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

Formats the value using the given formatter.

impl Default for Headers

fn default() -> Self

Returns the “default value” for a type.

impl IntoIterator for Headers

type Item = (String, String)

The type of the elements being iterated over.

type IntoIter = IntoIter<String, String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Headers

fn eq(&self, other: &Headers) -> 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.
