pub struct CacheControl { /* fields omitted */ }
Expand description
Cache-Control
header, defined in RFC7234
The Cache-Control
header field is used to specify directives for
caches along the request/response chain. Such cache directives are
unidirectional in that the presence of a directive in a request does
not imply that the same directive is to be given in the response.
ABNF
Cache-Control = 1#cache-directive
cache-directive = token [ "=" ( token / quoted-string ) ]
Example values
no-cache
private, community="UCI"
max-age=30
Example
use headers::CacheControl;
let cc = CacheControl::new();
Implementations
Construct a new empty CacheControl
header.
Check if the no-transform
directive is set.
Check if the only-if-cached
directive is set.
Set the no-cache
directive.
Set the no-store
directive.
Set the no-transform
directive.
Set the only-if-cached
directive.
Set the private
directive.
Set the public
directive.
Set the max-age
directive.
Set the max-stale
directive.
Set the min-fresh
directive.
Set the s-maxage
directive.
