• GET, HEAD, PUT
• OPTIONS, GET, PUT, POST, DELETE, HEAD, TRACE, CONNECT, PATCH, fOObAr
• ``

use headers::Allow;
use http::Method;

let allow = vec![Method::GET, Method::POST]
    .into_iter()
    .collect::<Allow>();

Implementations

impl Allow

pub fn iter<'a>(&'a self) -> impl Iterator<Item = Method> + 'a

Returns an iterator over Methods contained within.

Trait Implementations

impl Clone for Allow

fn clone(&self) -> Allow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Allow

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

Formats the value using the given formatter.

impl FromIterator<Method> for Allow

fn from_iter<I>(iter: I) -> Allow

where I: IntoIterator<Item = Method>,

Creates a value from an iterator.

impl Header for Allow

fn name() -> &'static HeaderName

The name of this header.

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

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

Decode this type from an iterator of HeaderValues.

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

where E: Extend<HeaderValue>,

Encode this type to a HeaderMap.

impl PartialEq for Allow

fn eq(&self, other: &Allow) -> 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.
