Struct CriticalCh 

pub struct CriticalCh(pub NonEmptySmallVec<16, ClientHint>);

Critical-CH header, defined by the Client Hints Infrastructure.

Sent alongside AcceptCh to mark a subset of the advertised ClientHints as critical: if the original request was not sent with these hints, a conforming user agent retries the request before handing the response to the page. Same wire format as Accept-CH (each hint under every spelling it answers to).

ABNF

Critical-CH = #client-hint-name

Example

use rama_utils::collections::non_empty_smallvec;
use rama_http_headers::{ClientHint, CriticalCh};

let critical_ch = CriticalCh(
    non_empty_smallvec![ClientHint::Ua, ClientHint::Platform; 16],
);

Implementations

impl CriticalCh

pub fn new(hint: ClientHint) -> CriticalCh

Create a CriticalCh advertising a single ClientHint.

Trait Implementations

impl Clone for CriticalCh

fn clone(&self) -> CriticalCh

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CriticalCh

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

Formats the value using the given formatter.

impl Eq for CriticalCh

impl HeaderDecode for CriticalCh

fn decode<'i, I>(values: &mut I) -> Result<CriticalCh, Error>

where I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

impl HeaderEncode for CriticalCh

fn encode<E>(&self, values: &mut E)

where E: Extend<HeaderValue>,

Encode this type to a HeaderValue, and add it to a container which has HeaderValue type as each element.

fn encode_to_value(&self) -> Option<HeaderValue>

Encode this header to HeaderValue.

impl PartialEq for CriticalCh

fn eq(&self, other: &CriticalCh) -> 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 StructuralPartialEq for CriticalCh

impl TypedHeader for CriticalCh

fn name() -> &'static HeaderName

The name of this header.
