pub struct KernelCache { /* private fields */ }

A bounded LRU of compiled kernels (docs/EAGER.md §8.2).

Implementations

impl KernelCache

pub fn new(capacity: usize) -> Self

A cache holding at most capacity compiled kernels (capacity is clamped to at least 1).

pub fn get_or_create<E>( &mut self, key: KernelCacheKey, create: impl FnOnce() -> Result<Box<dyn Kernel>, E>, ) -> Result<Arc<Mutex<Box<dyn Kernel>>>, E>

Return the cached kernel for key, compiling and inserting it via create on a miss (docs/EAGER.md §8.2 get_or_create).

pub fn stats(&self) -> CacheStats

Current cache statistics.
