Enum RemovalCause 

pub enum RemovalCause {
    Expired,
    Size,
    Explicit,
    Replaced,
}

The reason an entry was removed from the cache.

Variants

Expired

The entry’s TTL or TTI passed and the cache’s background maintenance reaped it. This is distinct from a get-time expiration check.

Size

The cache was at capacity and the eviction policy selected this entry for removal.

Explicit

The entry was removed by an explicit invalidate or clear call.

Replaced

The entry’s value was replaced by a subsequent insert with the same key.

Trait Implementations

impl Clone for RemovalCause

fn clone(&self) -> RemovalCause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RemovalCause

impl Debug for RemovalCause

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

Formats the value using the given formatter.

impl Eq for RemovalCause

impl Hash for RemovalCause

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 RemovalCause

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