template <typename T>class IndexedSlab
Defined at line 87 of file ../../src/connectivity/network/drivers/network-device/device/data_structs.h
A fixed capacity slab structure whose items are referenced by an index key.
The slab's capacity is set on creation. This slab is only capable of storing trivially
constructable and trivially destructible types.
This container is not thread-safe.
Public Methods
zx::result<std::unique_ptr<IndexedSlab<T>>> Create (uint32_t capacity)Creates a new slab with the given capacity and stores it in `out`.
Returns an error if the provided capacity is invalid, or it failed to allocate the required
memory.

uint32_t Push (T data)Pushes a new entry into the slab, returning a key to retrieve it.
Pushing into a full slab is invalid.

T & Get (uint32_t index)Gets the entry referenced by `index`.
Getting an invalid reference is invalid.
Defined at line 123 of file ../../src/connectivity/network/drivers/network-device/device/data_structs.h
void Free (uint32_t index)Frees the entry referenced by `index`, returning the slot back to the Slab.
It is invalid to free an index which is not currently occupied.
