[−][src]Struct typed_headers::ContentType
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
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]
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 self) -> Params<'a>
[src]
Returns an iterator over the parameters.
