Struct hyper::ext::ReasonPhrase

source ·
pub struct ReasonPhrase(/* private fields */);
Expand description

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§

source§

impl ReasonPhrase

source

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

Gets the reason phrase as bytes.

source

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

Converts a static byte slice to a reason phrase.

source

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.
