Implementations

impl ContentCoding

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

Returns a &'static str for a ContentCoding

Example

use headers::ContentCoding;

let coding = ContentCoding::BROTLI;
assert_eq!(coding.to_static(), "br");

pub fn from_str(s: &str) -> Self

Given a &str returns a ContentCoding

Note this will never fail, in the case of &str being an invalid content coding, will return ContentCoding::IDENTITY because 'identity' is generally always an accepted coding.

Example

use headers::ContentCoding;

let invalid = ContentCoding::from_str("not a valid coding");
assert_eq!(invalid, ContentCoding::IDENTITY);

let valid = ContentCoding::from_str("gzip");
assert_eq!(valid, ContentCoding::GZIP);

pub fn try_from_str(s: &str) -> Result<Self, ()>

Given a &str will try to return a ContentCoding

Different from ContentCoding::from_str(&str), if &str is an invalid content coding, it will return Err(())

Example

use headers::ContentCoding;

let invalid = ContentCoding::try_from_str("not a valid coding");
assert!(invalid.is_err());

let valid = ContentCoding::try_from_str("gzip");
assert_eq!(valid.unwrap(), ContentCoding::GZIP);

Trait Implementations

impl Clone for ContentCoding

fn clone(&self) -> ContentCoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentCoding

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

Formats the value using the given formatter.

impl From<ContentCoding> for HeaderValue

fn from(coding: ContentCoding) -> HeaderValue

Converts to this type from the input type.

impl PartialEq for ContentCoding

fn eq(&self, other: &ContentCoding) -> 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 ToString for ContentCoding

fn to_string(&self) -> String

Converts the given value to a String.
