Struct CacheControl 

pub struct CacheControl { /* private fields */ }

Cache-Control header, defined in RFC7234 with extensions in RFC8246

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();

pub fn must_understand(&self) -> bool

Check if the must-understand directive is set.

pub fn max_age(&self) -> Option<Duration>

Get the value of the max-age directive if set.

pub fn max_stale(&self) -> Option<Duration>

Get the value of the max-stale directive if set.

pub fn min_fresh(&self) -> Option<Duration>

Get the value of the min-fresh directive if set.

pub fn s_max_age(&self) -> Option<Duration>

Get the value of the s-maxage directive if set.

pub fn with_no_cache(self) -> Self

Set the no-cache directive.

pub fn with_no_store(self) -> Self

Set the no-store directive.

pub fn with_no_transform(self) -> Self

Set the no-transform directive.

pub fn with_only_if_cached(self) -> Self

Set the only-if-cached directive.

pub fn with_private(self) -> Self

Set the private directive.

pub fn with_public(self) -> Self

Set the public directive.

pub fn with_immutable(self) -> Self

Set the immutable directive.

pub fn with_must_revalidate(self) -> Self

Set the must-revalidate directive.

pub fn with_must_understand(self) -> Self

Set the must-understand directive.

pub fn with_max_age(self, duration: Duration) -> Self

Set the max-age directive.

pub fn with_max_stale(self, duration: Duration) -> Self

Set the max-stale directive.

pub fn with_min_fresh(self, duration: Duration) -> Self

Set the min-fresh directive.

pub fn with_s_max_age(self, duration: Duration) -> Self

Set the s-maxage directive.

Trait Implementations

impl Clone for CacheControl

fn clone(&self) -> CacheControl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheControl

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

Formats the value using the given formatter.

impl Header for CacheControl

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I: Iterator<Item = &'i HeaderValue>>( values: &mut I, ) -> Result<Self, Error>

Decode this type from an iterator of HeaderValues.

fn encode<E: Extend<HeaderValue>>(&self, values: &mut E)

Encode this type to a HeaderMap.

impl PartialEq for CacheControl

fn eq(&self, other: &CacheControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for CacheControl

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
