Struct hyper::ext::ReasonPhrase

pub struct ReasonPhrase(_);

A reason phrase in an HTTP/1 response.

Clients

For clients, a ReasonPhrase will be present in the extensions of the http::Response returned for a request if the reason phrase is different from the canonical reason phrase for the response’s status code. For example, if a server returns HTTP/1.1 200 Awesome, the ReasonPhrase will be present and contain Awesome, but if a server returns HTTP/1.1 200 OK, the response will not contain a ReasonPhrase.

use hyper::{Client, Uri};
use hyper::ext::ReasonPhrase;

let res = Client::new().get(Uri::from_static("http://example.com/non_canonical_reason")).await?;

// Print out the non-canonical reason phrase, if it has one...
if let Some(reason) = res.extensions().get::<ReasonPhrase>() {
    println!("non-canonical reason: {}", std::str::from_utf8(reason.as_bytes()).unwrap());
}

Servers

When a ReasonPhrase is present in the extensions of the http::Response written by a server, its contents will be written in place of the canonical reason phrase when responding via HTTP/1.

Implementations

impl ReasonPhrase

pub fn as_bytes(&self) -> &[u8]

Gets the reason phrase as bytes.

pub fn from_static(reason: &'static [u8]) -> Self

Converts a static byte slice to a reason phrase.

pub unsafe fn from_bytes_unchecked(reason: Bytes) -> Self

Converts a Bytes directly into a ReasonPhrase without validating.

Use with care; invalid bytes in a reason phrase can cause serious security problems if emitted in a response.

Trait Implementations

impl AsRef<[u8]> for ReasonPhrase

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ReasonPhrase

fn clone(&self) -> ReasonPhrase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReasonPhrase

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

Formats the value using the given formatter.

impl Hash for ReasonPhrase

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

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 Into<Bytes> for ReasonPhrase

fn into(self) -> Bytes

Converts this type into the (usually inferred) input type.

impl Ord for ReasonPhrase

fn cmp(&self, other: &ReasonPhrase) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ReasonPhrase> for ReasonPhrase

fn eq(&self, other: &ReasonPhrase) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<ReasonPhrase> for ReasonPhrase

fn partial_cmp(&self, other: &ReasonPhrase) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<&[u8]> for ReasonPhrase

type Error = InvalidReasonPhrase

The type returned in the event of a conversion error.

fn try_from(reason: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Bytes> for ReasonPhrase

type Error = InvalidReasonPhrase

The type returned in the event of a conversion error.

fn try_from(reason: Bytes) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for ReasonPhrase

type Error = InvalidReasonPhrase

The type returned in the event of a conversion error.

fn try_from(reason: String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<u8, Global>> for ReasonPhrase

type Error = InvalidReasonPhrase

The type returned in the event of a conversion error.

fn try_from(reason: Vec<u8>) -> Result<Self, Self::Error>

Performs the conversion.
