Enum cache::Reference

pub enum Reference<'a, V> {
    Spilled(V),
    Cached {
        guard: RwLockReadGuard<'a, ()>,
        ptr: *const ManuallyDrop<V>,
    },
}

A reference type to a value in the cache, either carrying the value itself (if an insert failed), or a readlock into the memory slab.

Variants

Spilled(V)

Value could not be put on the cache, and is returned as-is

Cached

Value resides in cache and is read-locked.

Fields of Cached

guard: RwLockReadGuard<'a, ()>	The readguard from a lock on the heap
ptr: *const ManuallyDrop<V>	A pointer to a value on the heap
