Enum ContentEncoding

#[non_exhaustive]
pub enum ContentEncoding {
    Identity,
    Brotli,
    Deflate,
    Gzip,
    Zstd,
}

Represents a supported content encoding.

Includes a commonly-used subset of media types appropriate for use as HTTP content encodings. See IANA HTTP Content Coding Registry.

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.

Identity

Indicates the no-op identity encoding.

I.e., no compression or modification.

Brotli

A format using the Brotli algorithm.

Deflate

A format using the zlib structure with deflate algorithm.

Gzip

Gzip algorithm.

Zstd

Zstd algorithm.

Implementations

impl ContentEncoding

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

Convert content encoding to string.

pub const fn to_header_value(self) -> HeaderValue

Convert content encoding to header value.

Trait Implementations

impl Clone for ContentEncoding

fn clone(&self) -> ContentEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentEncoding

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

Formats the value using the given formatter.

impl Default for ContentEncoding

fn default() -> ContentEncoding

Returns the “default value” for a type.

impl FromStr for ContentEncoding

type Err = ContentEncodingParseError

The associated error which can be returned from parsing.

fn from_str( enc: &str, ) -> Result<ContentEncoding, <ContentEncoding as FromStr>::Err>

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

impl Hash for ContentEncoding

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Header for ContentEncoding

fn name() -> HeaderName

Returns the name of the header field.

fn parse<T>(msg: &T) -> Result<ContentEncoding, ParseError>

where T: HttpMessage,

Parse the header from a HTTP message.

impl PartialEq for ContentEncoding

fn eq(&self, other: &ContentEncoding) -> 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 TryFrom<&str> for ContentEncoding

type Error = ContentEncodingParseError

The type returned in the event of a conversion error.

fn try_from( val: &str, ) -> Result<ContentEncoding, <ContentEncoding as TryFrom<&str>>::Error>

Performs the conversion.

impl TryIntoHeaderValue for ContentEncoding

type Error = InvalidHeaderValue

The type returned in the event of a conversion error.

fn try_into_value( self, ) -> Result<HeaderValue, <ContentEncoding as TryIntoHeaderValue>::Error>

Try to convert value to a HeaderValue.
