Struct http_types::content::accept::Accept [−][src]
pub struct Accept { /* fields omitted */ }
Expand description
Client header advertising which media types the client is able to understand.
Using content negotiation, the server then selects one of the proposals, uses
it and informs the client of its choice with the Content-Type
response
header. Browsers set adequate values for this header depending on the context
where the request is done: when fetching a CSS stylesheet a different value
is set for the request than when fetching an image, video or a script.
Specifications
Examples
use http_types::content::{Accept, MediaTypeProposal}; use http_types::{mime, Response}; let mut accept = Accept::new(); accept.push(MediaTypeProposal::new(mime::HTML, Some(0.8))?); accept.push(MediaTypeProposal::new(mime::XML, Some(0.4))?); accept.push(mime::PLAIN); let mut res = Response::new(200); let content_type = accept.negotiate(&[mime::XML])?; content_type.apply(&mut res); assert_eq!(res["Content-Type"], "application/xml;charset=utf-8");
Implementations
Create an instance of Accept
from a Headers
instance.
Push a directive into the list of entries.
Set the wildcard directive.
Sort the header directives by weight.
Headers with a higher q=
value will be returned first. If two
directives have the same weight, the directive that was declared later
will be returned first.
Determine the most suitable Content-Type
encoding.
Errors
If no suitable encoding is found, an error with the status of 406
will be returned.
Get the HeaderName
.
Get the HeaderValue
.
An iterator visiting all entries.
Trait Implementations
type Iter = IntoIter<HeaderValue>
type Iter = IntoIter<HeaderValue>
Returned iterator over header values which this type may correspond to.
Converts this object to an iterator of resolved HeaderValues
.
