Pre-allocated Storage for a Uniform Data Type

slab⮳ provides pre-allocated storage for a single data type. If many values of a single type are being allocated, it can be more efficient to pre-allocate the necessary storage. Since the size of the type is uniform, memory fragmentation can be avoided. Storing, clearing, and lookup operations become very cheap.

While slab may look like other Rust collections, it is not intended to be used as a general purpose collection. The primary difference between slab and Vec is that slab⮳ returns the key when storing the value.

It is important to note that keys may be reused. In other words, once a value associated with a given key is removed from a slab, that key may be returned from future calls to insert.
