Enum CacheEvent 

pub enum CacheEvent {
    Hit,
    Miss,
    Expire,
    Clear,
}

Single-phase cache event classifier. Unlike Verb these events have no start/done split — a cache hit is observable in one phase. The label set is closed at the type level so audit consumers can switch on it without parsing.

Variants

Hit

Miss

Expire

Clear

Trait Implementations

impl Clone for CacheEvent

fn clone(&self) -> CacheEvent

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for CacheEvent

impl Debug for CacheEvent

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

impl Eq for CacheEvent

impl PartialEq for CacheEvent

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