Enum ServerCachePreference

pub enum ServerCachePreference {
    None,
    QueryMatters,
    Full,
    MaxAge(Duration),
}

The preference for caching the item on the server.

This can be overridden by the cache-control or kvarn-cache-control headers.

Note: It’s only a preference. Disabling the cache in compile-time will disable this behaviour. Some other factors also play a role, such as number of cached Vary responses on a page.

Variants

None

Will not cache response

QueryMatters

Will cache response with query

Full

Query does not matter and will be discarded

MaxAge(Duration)

Sets a max age for the content. Query will be discarded in cache, same as Self::Full.

Implementations

impl ServerCachePreference

pub fn cache(self, cache_action: CacheAction, method: &Method) -> bool

If a response with cache_action (from host::CacheAction) should be cached.

pub fn query_matters(self) -> bool

If query matters in cache.

Ultimately dictates which variant of UriKey should be cached.

Trait Implementations

impl Clone for ServerCachePreference

fn clone(&self) -> ServerCachePreference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ServerCachePreference

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

Formats the value using the given formatter.

impl FromStr for ServerCachePreference

type Err = CachePreferenceError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ServerCachePreference

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ServerCachePreference

fn eq(&self, other: &ServerCachePreference) -> 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.
