Struct salvo::http::headers::ContentType [−][src]
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 headers::ContentType; let ct = ContentType::json();
