• RFC 7231, section 5.1.1: Expect

Examples

use http_types::Response;
use http_types::other::Expect;

let expect = Expect::new();

let mut res = Response::new(200);
expect.apply(&mut res);

let expect = Expect::from_headers(res)?.unwrap();
assert_eq!(expect, Expect::new());

Implementations

impl Expect

pub fn new() -> Self

Create a new instance of Expect.

pub fn from_headers(headers: impl AsRef<Headers>) -> Result<Option<Self>>

Create an instance of Expect from a Headers instance.

pub fn apply(&self, headers: impl AsMut<Headers>)

Insert a HeaderName + HeaderValue pair into a Headers instance.

pub fn name(&self) -> HeaderName

Get the HeaderName.

pub fn value(&self) -> HeaderValue

Get the HeaderValue.

Trait Implementations

impl Debug for Expect

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

Formats the value using the given formatter.

impl Ord for Expect

fn cmp(&self, other: &Expect) -> 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 Expect

fn eq(&self, other: &Expect) -> 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 Expect

fn partial_cmp(&self, other: &Expect) -> 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 ToHeaderValues for Expect

type Iter = IntoIter<HeaderValue>

Returned iterator over header values which this type may correspond to.

fn to_header_values(&self) -> Result<Self::Iter>

Converts this object to an iterator of resolved HeaderValues.

impl Eq for Expect

impl StructuralPartialEq for Expect
