Struct Headers

Source
pub struct Headers { /* private fields */ }
Expand description

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§

Source§

impl Headers

Source

pub fn new() -> Headers

Init an empty header struct

Source

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.

Source

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

Retrieve the value at the given key

Source

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

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

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

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