Struct L1Entry 

pub struct L1Entry {
    pub result: CachedResult,
    pub query: String,
    pub access_count: AtomicU64,
    pub last_access: Instant,
}

Entry in the L1 hot cache

access_count is an AtomicU64 so cache hits can bump it under a read lock on the containing map — touch() takes &self, not &mut self. last_access is deliberately cosmetic (not consulted by LRU eviction, which uses a separate ordered queue) and is not updated per-access.

Fields

result: CachedResult

The cached result

query: String

Original query string (for exact match)

access_count: AtomicU64

Access count (atomic so hits only need a read lock on the map)

last_access: Instant

Creation / last-put time. Not updated on hits (LRU uses a separate ordered queue), so this reflects when the entry was first stored.

Implementations

impl L1Entry

pub fn new(query: String, result: CachedResult) -> Self

Create a new L1 cache entry

pub fn touch(&self)

Record an access to this entry (lock-free — takes &self).

pub fn access_count(&self) -> u64

Get the current access count.

pub fn is_expired(&self) -> bool

Check if this entry has expired

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

Formats the value using the given formatter.
