Struct rocket::http::ContentType
source · pub struct ContentType(pub MediaType);
Expand description
Representation of HTTP Content-Types.
Usage
ContentType
s should rarely be created directly. Instead, an associated
constant should be used; one is declared for most commonly used content
types.
Example
A Content-Type of text/html; charset=utf-8
can be instantiated via the
HTML
constant:
use rocket::http::ContentType;
let html = ContentType::HTML;
Header
ContentType
implements Into<Header>
. As such, it can be used in any
context where an Into<Header>
is expected:
use rocket::http::ContentType;
use rocket::response::Response;
let response = Response::build().header(ContentType::HTML).finalize();

Implementations§
source§impl ContentType
impl ContentType
sourcepub fn new<T, S>(top: T, sub: S) -> ContentTypewhere
T: Into<Cow<'static, str>>,
S: Into<Cow<'static, str>>,
pub fn new<T, S>(top: T, sub: S) -> ContentTypewhere T: Into<Cow<'static, str>>, S: Into<Cow<'static, str>>,
Creates a new ContentType
with top-level type top
and subtype sub
.
This should only be used to construct uncommon or custom content
types. Use an associated constant for everything else.
Example
Create a custom application/x-person
content type:
use rocket::http::ContentType;
let custom = ContentType::new("application", "x-person");
assert_eq!(custom.top(), "application");
assert_eq!(custom.sub(), "x-person");
sourcepub fn parse_flexible(name: &str) -> Option<ContentType>
pub fn parse_flexible(name: &str) -> Option<ContentType>
Flexibly parses name
into a ContentType
. The parse is flexible because, in addition to strictly correct content types, it recognizes the following shorthands:
- “any” -
ContentType::Any
- “binary” -
ContentType::Binary
- “bytes” -
ContentType::Bytes
- “html” -
ContentType::HTML
- “plain” -
ContentType::Plain
- “text” -
ContentType::Text
- “json” -
ContentType::JSON
- “msgpack” -
ContentType::MsgPack
- “form” -
ContentType::Form
- “js” -
ContentType::JavaScript
- “css” -
ContentType::CSS
- “multipart” -
ContentType::FormData
- “xml” -
ContentType::XML
- “pdf” -
ContentType::PDF
- “markdown” -
ContentType::Markdown
- “md” -
ContentType::Markdown
For regular parsing, use the
ContentType::from_str()
method.
Example
Using a shorthand:
use rocket::http::ContentType;
let html = ContentType::parse_flexible("html");
assert_eq!(html, Some(ContentType::HTML));
let json = ContentType::parse_flexible("json");
assert_eq!(json, Some(ContentType::JSON));
Using the full content-type:
use rocket::http::ContentType;
let html = ContentType::parse_flexible("text/html; charset=utf-8");
assert_eq!(html, Some(ContentType::HTML));
let json = ContentType::parse_flexible("application/json");
assert_eq!(json, Some(ContentType::JSON));
let custom = ContentType::parse_flexible("application/x+custom");
assert_eq!(custom, Some(ContentType::new("application", "x+custom")));
An unrecognized content-type:
use rocket::http::ContentType;
let foo = ContentType::parse_flexible("foo");
assert_eq!(foo, None);
let bar = ContentType::parse_flexible("foo/bar/baz");
assert_eq!(bar, None);
sourcepub fn from_extension(ext: &str) -> Option<ContentType>

assert_eq!(xml, Some(ContentType::XML));
let xml = ContentType::from_extension("XML");
assert_eq!(xml, Some(ContentType::XML));
An unrecognized content type:
use rocket::http::ContentType;
let foo = ContentType::from_extension("foo");
assert!(foo.is_none());
sourcepub fn with_params<K, V, P>(self, parameters: P) -> ContentTypewhere

.with_params([("name", "bob"), ("ref", "2382")]);
assert_eq!(mt.to_string(), "text/person; name=bob; ref=2382".to_string());
sourcepub fn media_type(&self) -> &MediaType
pub fn media_type(&self) -> &MediaType

Methods from Deref<Target = MediaType>§
sourcepub fn top(&self) -> &UncasedStr
pub fn top(&self) -> &UncasedStr
Returns the top-level type for this media type. The return type,
UncasedStr
, has caseless equality comparison and hashing.
Example
use rocket::http::MediaType;
let plain = MediaType::Plain;
assert_eq!(plain.top(), "text");
assert_eq!(plain.top(), "TEXT");
assert_eq!(plain.top(), "Text");
sourcepub fn sub(&self) -> &UncasedStr
pub fn sub(&self) -> &UncasedStr
Returns the subtype for this media type. The return type,
UncasedStr
, has caseless equality comparison and hashing.
Example
use rocket::http::MediaType;
let plain = MediaType::Plain;
assert_eq!(plain.sub(), "plain");
assert_eq!(plain.sub(), "PlaIN");
assert_eq!(plain.sub(), "pLaIn");
sourcepub fn specificity(&self) -> u8
pub fn specificity(&self) -> u8
Returns a u8
representing how specific the top-level type and subtype
of this media type are.
The return value is either 0
, 1
, or 2
, where 2
is the most
specific. A 0
is returned when both the top and sublevel types are
*
. A 1
is returned when only one of the top or sublevel types is
*
, and a 2
is returned when neither the top or sublevel types are
*
.
Example
use rocket::http::MediaType;
let mt = MediaType::Plain;
assert_eq!(mt.specificity(), 2);
let mt = MediaType::new("text", "*");
assert_eq!(mt.specificity(), 1);
let mt = MediaType::Any;
assert_eq!(mt.specificity(), 0);
sourcepub fn exact_eq(&self, other: &MediaType) -> bool
pub fn exact_eq(&self, other: &MediaType) -> bool
Compares self
with other
and returns true
if self
and other
are exactly equal to each other, including with respect to their
parameters and their order.
This is different from the PartialEq
implementation in that it
considers parameters. In particular, Eq
implies PartialEq
but
PartialEq
does not imply Eq
. That is, if PartialEq
returns false,
this function is guaranteed to return false. Similarly, if exact_eq
returns true
, PartialEq
is guaranteed to return true. However, if
PartialEq
returns true
, exact_eq
function may or may not return
true
.
Example
use rocket::http::MediaType;
let plain = MediaType::Plain;
let plain2 = MediaType::new("text", "plain").with_params(("charset", "utf-8"));
let just_plain = MediaType::new("text", "plain");
// The `PartialEq` implementation doesn't consider parameters.
assert!(plain == just_plain);
assert!(just_plain == plain2);
assert!(plain == plain2);
// While `exact_eq` does.
assert!(!plain.exact_eq(&just_plain));
assert!(!plain2.exact_eq(&just_plain));
assert!(plain.exact_eq(&plain2));
sourcepub fn params(&self) -> impl Iterator<Item = (&UncasedStr, &str)>
pub fn params(&self) -> impl Iterator<Item = (&UncasedStr, &str)>
Returns an iterator over the (key, value) pairs of the media type’s parameter list. The iterator will be empty if the media type has no parameters.
Example
The MediaType::Plain
type has one parameter: charset=utf-8
:
use rocket::http::MediaType;
let plain = MediaType::Plain;
let (key, val) = plain.params().next().unwrap();
assert_eq!(key, "charset");
assert_eq!(val, "utf-8");
The MediaType::PNG
type has no parameters:
use rocket::http::MediaType;
let png = MediaType::PNG;
assert_eq!(png.params().count(), 0);
sourcepub fn param<'a>(&'a self, name: &str) -> Option<&'a str>
pub fn param<'a>(&'a self, name: &str) -> Option<&'a str>
Returns the first parameter with name name
, if there is any.
sourcepub fn extension(&self) -> Option<&UncasedStr>
pub fn extension(&self) -> Option<&UncasedStr>
Returns the most common file extension associated with the Media-Type self
if it is known. Otherwise, returns None
. The currently recognized extensions are identical to those in MediaType::from_extension()
with the most common extension being the first extension appearing in the list for a given Media-Type .
Example
Known extension:
use rocket::http::MediaType;
assert_eq!(MediaType::JSON.extension().unwrap(), "json");
assert_eq!(MediaType::JPEG.extension().unwrap(), "jpeg");
assert_eq!(MediaType::JPEG.extension().unwrap(), "JPEG");
assert_eq!(MediaType::PDF.extension().unwrap(), "pdf");
An unknown extension:
use rocket::http::MediaType;
let foo = MediaType::new("foo", "bar");
assert!(foo.extension().is_none());

source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the foreground set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red()
and
green()
, which have the same functionality but are
pithier.
Example
Set foreground color to white using fg()
:
use yansi::{Paint, Color};
painted.fg(Color::White);
Set foreground color to white using white()
.
use yansi::Paint;
painted.white();

source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the background set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red()
and
on_green()
, which have the same functionality but
are pithier.
Example
Set background color to red using fg()
:
use yansi::{Paint, Color};
painted.bg(Color::Red);
Set background color to red using on_red()
.
use yansi::Paint;
painted.on_red();

.
Example
println!("{}", value.on_bright_white());
source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute
value
.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold()
and
underline()
, which have the same functionality
but are pithier.
Example
Make text bold using attr()
:
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);
Make text bold using using bold()
.
use yansi::Paint;
painted.bold();
source§fn underline(&self) -> Painted<&T>

set to
Attribute::Underline
.
Example
println!("{}", value.underline());
source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Returns self
with the
attr()
set to
Attribute::RapidBlink
.
Example
println!("{}", value.rapid_blink());
source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi
Quirk
value
.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask()
and
wrap()
, which have the same functionality but are
pithier.
Example
Enable wrapping using .quirk()
:
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);
Enable wrapping using wrap()
.
use yansi::Paint;
painted.wrap();
source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition
value
applies. Replaces any previous condition.
See the crate level docs for more details.
Example
Enable styling painted
only when both stdout
and stderr
are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
