- Memory Slices - efficient way to allocate groups of equal-sized chunks of memory.
- Memory Chunks - deprecated way to allocate groups of equal-sized chunks of memory.
- Doubly-Linked Lists - linked lists containing integer values or pointers to data, with the ability to iterate over the list in both directions.
- Singly-Linked Lists - linked lists containing integer values or pointers to data, limited to iterating over the list in one direction.
- Double-ended Queues - double-ended queue data structure.
- Trash Stacks - maintain a stack of unused allocated memory chunks.
- Hash Tables - associations between keys and values so that given a key the value can be found quickly.
- Strings - text buffers which grow automatically as text is added.
- String Chunks - efficient storage of groups of strings.
- Arrays - arrays of arbitrary elements which grow automatically as elements are added.
- Pointer Arrays - arrays of pointers to any type of data, which grow automatically as new elements are added.
- Byte Arrays - arrays of bytes, which grow automatically as elements are added.
- Balanced Binary Trees - a sorted collection of key/value pairs optimized for searching and traversing in order.
- N-ary Trees - trees of data with any number of branches.
- Quarks - a 2-way association between a string and a unique integer identifier.
- Keyed Data Lists - lists of data elements which are accessible by a string or GQuark identifier.
- Datasets - associate groups of data elements with particular memory locations.
- Relations and Tuples - tables of data which can be indexed on any number of fields.
- Caches - caches allow sharing of complex data structures to save resources.
