[][src]Struct hyper::header::ContentType

pub struct ContentType(pub Mime);

Content-Type header, defined in RFC7231

The Content-Type header field indicates the media type of the associated representation: either the representation enclosed in the message payload or the selected representation, as determined by the message semantics. The indicated media type defines both the data format and how that data is intended to be processed by a recipient, within the scope of the received message semantics, after any content codings indicated by Content-Encoding are decoded.

Although the mime crate allows the mime options to be any slice, this crate forces the use of Vec. This is to make sure the same header can't have more than 1 type. If this is an issue, it's possible to implement Header on a custom struct.

ABNF

Content-Type = media-type

Example values

Examples

use hyper::header::{Headers, ContentType};

let mut headers = Headers::new();

headers.set(
    ContentType::json()
);
use hyper::header::{Headers, ContentType};
use hyper::mime;

let mut headers = Headers::new();

headers.set(
    ContentType(mime::TEXT_HTML)
);

Methods from Deref<Target = Mime>

pub fn type_(&self) -> Name[src]

Get the top level media type for this Mime.

Example

let mime = mime::TEXT_PLAIN;
assert_eq!(mime.type_(), "text");
assert_eq!(mime.type_(), mime::TEXT);

pub fn subtype(&self) -> Name[src]

Get the subtype of this Mime.

Example

let mime = mime::TEXT_PLAIN;
assert_eq!(mime.subtype(), "plain");
assert_eq!(mime.subtype(), mime::PLAIN);

pub fn suffix(&self) -> Option<Name>[src]

Get an optional +suffix for this Mime.

Example

let svg = "image/svg+xml".parse::<mime::Mime>().unwrap();
assert_eq!(svg.suffix(), Some(mime::XML));
assert_eq!(svg.suffix().unwrap(), "xml");


assert!(mime::TEXT_PLAIN.suffix().is_none());

pub fn get_param<'a, N>(&'a self, attr: N) -> Option<Name<'a>> where
    N: PartialEq<Name<'a>>, 
[src]

Look up a parameter by name.

Example

let mime = mime::TEXT_PLAIN_UTF_8;
assert_eq!(mime.get_param(mime::CHARSET), Some(mime::UTF_8));
assert_eq!(mime.get_param("charset").unwrap(), "utf-8");
assert!(mime.get_param("boundary").is_none());

let mime = "multipart/form-data; boundary=ABCDEFG".parse::<mime::Mime>().unwrap();
assert_eq!(mime.get_param(mime::BOUNDARY).unwrap(), "ABCDEFG");

pub fn params(&'a self) -> Params<'a>[src]

Returns an iterator over the parameters.

pub fn essence_str(&self) -> &str[src]

Return a &str of the Mime's "essence".
