Struct 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.

ABNF

Content-Type = media-type

Example values

• text/html; charset=utf-8
• application/json

Tuple Fields

0: Mime

Methods from Deref<Target = Mime>

pub fn type_(&self) -> Name<'_>

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<'_>

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<'_>>

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>>,

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>(&'a self) -> Params<'a>

Returns an iterator over the parameters.

pub fn essence_str(&self) -> &str

Return a &str of the Mime’s “essence”.

Trait Implementations

impl Clone for ContentType

fn clone(&self) -> ContentType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentType

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

Formats the value using the given formatter.

impl Deref for ContentType

type Target = Mime

The resulting type after dereferencing.

fn deref(&self) -> &Mime

Dereferences the value.

impl DerefMut for ContentType

fn deref_mut(&mut self) -> &mut Mime

Mutably dereferences the value.

impl Header for ContentType

fn name() -> &'static HeaderName

Returns the name of this header.

fn from_values( values: &mut ValueIter<'_, HeaderValue>, ) -> Result<Option<ContentType>, Error>

Parses the header from the raw value bytes.

fn to_values(&self, values: &mut ToValues<'_>)

Serializes the header to raw values.

impl PartialEq for ContentType

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