Struct MemoryManagerSlot 

pub struct MemoryManagerSlot(/* private fields */);

MemoryManagerSlot

A usable physical ic-stable-structures::MemoryManager allocation ID.

Construction and deserialization reject the unallocated-bucket sentinel (255), so reading the ID is infallible. A slot is an identity, not authority to open memory; that still requires committed allocation validation.

Serde encodes the numeric ID directly. Decoding uses the same checked constructor, so serialized DTOs cannot introduce the sentinel.
