Struct CacheEntry 

pub struct CacheEntry<V> {
    pub value: V,
    pub expires_at: Option<Instant>,
}

A cache entry that optionally expires at a given instant.

Used internally by all cache implementations to support per-entry TTL. Callers interact with the value type V via the Cache trait methods; CacheEntry is exposed for advanced use cases (e.g. custom wrappers).

Fields

value: V

The stored value.

expires_at: Option<Instant>

Optional expiry time. None means the entry never expires.

Implementations

impl<V> CacheEntry<V>

pub fn new(value: V) -> Self

Create a non-expiring entry.

pub fn with_ttl(value: V, ttl: Duration) -> Self

Create an entry that expires after ttl from now.

pub fn is_expired(&self) -> bool

Return true if this entry has expired (i.e. its deadline has passed).
