Implementations

impl MemoizeCache

pub fn new() -> Self

pub const fn with_max_entries(self, n: usize) -> Self

pub const fn with_max_bytes(self, b: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&mut self, key: &CacheKey) -> Option<Value>

Look up a cached scalar value. On hit, re-promotes the entry to the LRU front and bumps hit_count. On miss, returns None (caller runs the subquery + inserts).

pub fn insert(&mut self, key: CacheKey, value: Value)

Insert a freshly-computed scalar value. Caller must have get-missed first (the cache doesn’t dedupe inserts). Evicts LRU entries until both caps are satisfied.
