Struct CacheEntry 

pub struct CacheEntry {
    pub bindings: Vec<HashMap<String, String>>,
    pub is_final: bool,
    pub inserted_at: Instant,
    pub ttl: Duration,
    pub hit_count: u64,
}

A single cached inference result.

Fields

bindings: Vec<HashMap<String, String>>

is_final: bool

true if the result is definitive (no further answers possible).

inserted_at: Instant

Wall-clock instant at which this entry was inserted.

ttl: Duration

Maximum time this entry may be retained.

hit_count: u64

Number of times this entry has been returned via VersionedInferenceCache::get.

Implementations

impl CacheEntry

pub fn new(bindings: Vec<HashMap<String, String>>, is_final: bool) -> Self

pub fn with_ttl( bindings: Vec<HashMap<String, String>>, is_final: bool, ttl: Duration, ) -> Self

Create a new CacheEntry with a custom TTL.

pub fn is_expired(&self, now: Instant) -> bool

Returns true if this entry’s TTL has elapsed relative to now.
