Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl ContentType

pub fn from_header(header: &HeaderValue) -> Option<Self>

Attempts to parse the given HeaderValue into a ContentType by treating it as a MIME type.

Note that, along with official MIME types, this method also recognizes some unofficial MIME types that are commonly used in practice.

let header = HeaderValue::from_static("application/json");
let content_type = ContentType::from_header(&header).unwrap();

assert_eq!(content_type, ContentType::Json);

let header = HeaderValue::from_static("application/vnd.msgpack");
let content_type = ContentType::from_header(&header).unwrap();

assert_eq!(content_type, ContentType::MsgPack);

let header = HeaderValue::from_static("application/x-msgpack");
let content_type = ContentType::from_header(&header).unwrap();

assert_eq!(content_type, ContentType::MsgPack);

pub fn as_str(&self) -> &'static str

Returns the MIME type as a string slice.

let content_type = ContentType::Json;

assert_eq!(content_type.as_str(), "application/json");

pub fn into_header(self) -> HeaderValue

Converts the ContentType into a HeaderValue.

let content_type = ContentType::Json;
let header = content_type.into_header();

assert_eq!(header, HeaderValue::from_static("application/json"));

let content_type = ContentType::MsgPack;
let header = content_type.into_header();

assert_eq!(header, HeaderValue::from_static("application/vnd.msgpack"));

let content_type = ContentType::Yaml;
let header = content_type.into_header();

assert_eq!(header, HeaderValue::from_static("application/x-yaml"));

let content_type = ContentType::Toml;
let header = content_type.into_header();

assert_eq!(header, HeaderValue::from_static("text/toml"));

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 Default for ContentType

fn default() -> Self

Returns the “default value” for a type.

impl Display for ContentType

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

Formats the value using the given formatter.

impl From<Accept> for ContentType

fn from(accept: Accept) -> Self

Converts to this type from the input type.

impl<S> FromRequestParts<S> for ContentType

where S: Sync,

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.

impl FromStr for ContentType

type Err = FromStrError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

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.

impl Copy for ContentType

impl Eq for ContentType
