Struct SpecializationCache 

pub struct SpecializationCache<V> { /* private fields */ }

Small exact-key LRU for compiled shape specializations.

This portable cache is deliberately synchronization-free. A concurrent provider should put a lock or single-flight compilation state around it at its existing program/queue owner boundary.

Implementations

impl<V> SpecializationCache<V>

pub fn new(capacity: NonZeroUsize) -> Self

pub const fn capacity(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&mut self, key: &SpecializationKey) -> Option<&V>

pub fn get_mut(&mut self, key: &SpecializationKey) -> Option<&mut V>

pub fn insert( &mut self, key: SpecializationKey, value: V, ) -> Result<Option<V>, CacheInsertError<V>>

Insert or replace a specialization, returning the replaced or evicted compiled value.
