Struct Allow

pub struct Allow { /* private fields */ }

List the set of methods supported by a resource.

Specifications

• RFC 7231, section 7.4.1: Allow

Examples

use http_types_rs::{Method, Response};
use http_types_rs::server::Allow;

let mut allow = Allow::new();
allow.insert(Method::Put);
allow.insert(Method::Post);

let mut res = Response::new(200);
res.insert_header(&allow, &allow);

let allow = Allow::from_headers(res)?.unwrap();
assert!(allow.contains(Method::Put));
assert!(allow.contains(Method::Post));

Implementations

impl Allow

pub fn new() -> Self

Create a new instance of Allow.

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

Create a new instance from headers.

pub fn insert(&mut self, method: Method)

Push a method into the set of methods.

pub fn iter(&self) -> Iter<'_>

An iterator visiting all server entries.

pub fn contains(&self, method: Method) -> bool

Returns true if the header contains the Method.

Trait Implementations

impl Debug for Allow

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

Formats the value using the given formatter.

impl Header for Allow

fn header_name(&self) -> HeaderName

Access the header’s name.

fn header_value(&self) -> HeaderValue

Access the header’s value.

fn apply_header<H: AsMut<Headers>>(&self, headers: H)

Insert the header name and header value into something that looks like a Headers map.
