Struct Rtt 

pub struct Rtt(/* private fields */);

Available on crate feature http only.

Sec-CH-RTT client hint: the approximate round-trip time on the application layer, modelled as a Duration.

Unlike transport-layer RTT this includes server processing time. The value is rounded to the nearest 25 ms to limit fingerprinting. See the Network Information API.

Corresponds to ClientHint::Rtt; encoded as Sec-CH-RTT.

Example

use std::time::Duration;
use rama_http_headers::Rtt;

let rtt = Rtt::from_millis(100);
assert_eq!(Duration::from(rtt), Duration::from_millis(100));

Implementations

impl Rtt

pub const HINT: ClientHint = ClientHint::Rtt

The ClientHint this typed value parser corresponds to.

pub const fn from_millis(millis: u64) -> Rtt

Create an Rtt hint from a round-trip time in milliseconds.

pub const fn as_millis(self) -> u64

Returns the round-trip time in milliseconds.

pub const fn as_duration(self) -> Duration

Returns the round-trip time as a Duration.

Trait Implementations

impl Clone for Rtt

fn clone(&self) -> Rtt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rtt

impl Debug for Rtt

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

Formats the value using the given formatter.

impl Eq for Rtt

impl From<Rtt> for Duration

fn from(rtt: Rtt) -> Duration

Converts to this type from the input type.

impl Hash for Rtt

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 HeaderDecode for Rtt

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

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

Decode this type from an iterator of HeaderValues.

impl HeaderEncode for Rtt

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 Ord for Rtt

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Rtt

fn eq(&self, other: &Rtt) -> 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 PartialOrd for Rtt

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StructuralPartialEq for Rtt

impl TypedHeader for Rtt

fn name() -> &'static HeaderName

The name of this header.
