Enum CacheHint

pub enum CacheHint {
    Normal,
    Low,
}

Hint for the cache eviction algorithm to decide the priority of the specific entry if needed.

The meaning of the hint differs in each cache eviction algorithm, and some of them can be ignore by specific algorithm.

If the given cache hint does not suitable for the cache eviction algorithm that is active, the algorithm may modify it to a proper one.

For more details, please refer to the document of each enum options.

Variants

Normal

The default hint shared by all cache eviction algorithms.

Low

Suggest the priority of the entry is low.

Used by LRU.

Trait Implementations

impl Clone for CacheHint

fn clone(&self) -> CacheHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CacheHint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CacheHint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheHint

fn eq(&self, other: &CacheHint) -> 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 Serialize for CacheHint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
