Linked List implementation that uses a static array as backing memory for an arbitrary number of linked lists.
To create a linked list you first have to create a StaticLinkedListBackingArray
passing to it an array of u8
.
Then, you can create any number of lists backed by that array using new_list()
. Note that creating arrays of zero-sized types
is not possible.
Since the created lists share the backing arrays underlying memory the total number of entries across all lists cannot exceed the array's capacity.
The list needs some memory in the buffer for its metadata (pointers to the next element). If the buffer used to create a
StaticLinkedListBackingArray
is not big enough to hold n
entries of data plus list metadata, the array will only have a
capacity of n - 1
entries. The remaining bytes will be wasted. The capacity_for()
function was designed to calculate the
exact amount of bytes necessary for holding n
entries of data.
