Struct ContentType

pub struct ContentType(/* private fields */);
Expand description

Content-Type header, defined in RFC7231

The Content-Type header field indicates the media type of the associated representation: either the representation enclosed in the message payload or the selected representation, as determined by the message semantics. The indicated media type defines both the data format and how that data is intended to be processed by a recipient, within the scope of the received message semantics, after any content codings indicated by Content-Encoding are decoded.

Although the mime crate allows the mime options to be any slice, this crate forces the use of Vec. This is to make sure the same header can’t have more than 1 type. If this is an issue, it’s possible to implement Header on a custom struct.

§ABNF

Content-Type = media-type

§Example values

  • text/html; charset=utf-8
  • application/json

§Examples

use rama_http_headers::ContentType;

let ct = ContentType::json();
