[][src]Struct hyper::header::Headers

pub struct Headers { /* fields omitted */ }

A map of header fields on requests and responses.

Methods

impl Headers[src]

pub fn new() -> Headers[src]

Creates a new, empty headers map.

pub fn set<H: Header + HeaderFormat>(&mut self, value: H)[src]

Set a header field to the corresponding value.

The field is determined by the type of the value being set.

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

Access the raw value of a header.

Prefer to use the typed getters instead.

Example:

let raw_content_type = headers.get_raw("content-type");

pub fn set_raw<K: Into<Cow<'static, str>>>(
    &mut self,
    name: K,
    value: Vec<Vec<u8>>
)
[src]

Set the raw value of a header, bypassing any typed headers.

Note: This will completely replace any current value for this header name.

Example:

headers.set_raw("content-length", vec![b"5".to_vec()]);

pub fn append_raw<K: Into<Cow<'static, str>>>(
    &mut self,
    name: K,
    value: Vec<u8>
)
[src]

Append a value to raw value of this header.

If a header already contains a value, this will add another line to it.

If a header doesnot exist for this name, a new one will be created with the value.

Example:

headers.append_raw("x-foo", b"bar".to_vec());
headers.append_raw("x-foo", b"quux".to_vec());

pub fn remove_raw(&mut self, name: &str)[src]

Remove a header set by set_raw

pub fn get<H: Header + HeaderFormat>(&self) -> Option<&H>[src]

Get a reference to the header field's value, if it exists.

pub fn get_mut<H: Header + HeaderFormat>(&mut self) -> Option<&mut H>[src]

Get a mutable reference to the header field's value, if it exists.

pub fn has<H: Header + HeaderFormat>(&self) -> bool[src]

Returns a boolean of whether a certain header is in the map.

Example:

let has_type = headers.has::<ContentType>();

pub fn remove<H: Header + HeaderFormat>(&mut self) -> bool[src]

Removes a header from the map, if one existed. Returns true if a header has been removed.

Important traits for HeadersItems<'a>
pub fn iter(&self) -> HeadersItems[src]

Returns an iterator over the header fields.

pub fn len(&self) -> usize[src]

Returns the number of headers in the map.

pub fn clear(&mut self)[src]

Remove all headers from the map.
