@bitSet, @bitGet are helper functions to test and set bit. @bitIndex is an arbitrary large bit index to test/set. @ptr points to the first byte of lar

Return byte at specified index. This view must NOT be null. Caller is responsible for ensuring the index is within bounds.

given two memory pools that are full, try to free some allocations from one pool and still ensure that other is full across all alloc classes.

Clamp the input into range [lower, upper]

Compress the given slabIdx and allocIdx into a 32-bit compressed pointer.

Create a DynamicRandomAP with given target rate that accepts all items before the first update and treats odd lenth key as bypassed.

Bumps down the reference count @return Refcount with control bits. When it is zero, we know for certain no one has access to it. @throw RefcountUnde

Remove the put context by passing a reference to it. After this, the caller is supposed to not refer to it anymore.
