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

pub struct Headers { /* fields omitted */ }

A map of header fields on requests and responses.

Methods

impl Headers
[src]

Creates a new, empty headers map.

Set a header field to the corresponding value.

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

Access the raw value of a header.

Prefer to use the typed getters instead.

Example:

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

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

Example:

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

Remove a header set by set_raw

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

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

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

Example:

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

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

Important traits for HeadersItems<'a>

Returns an iterator over the header fields.

Returns the number of headers in the map.

Remove all headers from the map.
