When working on video game engines we are predominantly dealing with collections of data where: To meet these requirements, game developers tend to either (a) develop their own custom containers for given scenario or (b) develop workarounds for the failings of std::vector.

If it is not empty, it pops an erased element location off the stack and reuses that memory address for the newly-inserted element. It can be modified and used in commercial software.
If you erase all elements in any given group in a colony, the group is removed from the colony's chain and released to the OS - at that point any erased element locations present in the erased-location stack are also removed. Authors are not liable for any damages arising from its use.
Memory from erased elements is either reused by subsequent insertions or released to the OS on-the-fly.
It achieves these ends by via a number of new approaches: a jump-counting skipfield (instead of a boolean field), a linked chain of increasingly-large memory blocks (instead of a singular memory block or vector of blocks), and a custom internal reduced stack (based on plf::stack) to enable erased memory location re-use.
Specifically it provides better performance than other std:: library containers when: As explored further in the benchmarks there are some vector/deque modifications which can outperform colony during iteration while maintaining pointer validity, but at a cost to usability and memory usage.
Colony's other advantages include the freeing and recycling of unused memory on-the-fly, the guaranteed stability of pointers/references/iterators to non-erased elements (which makes programming with containers of inter-related data structures faster and much easier), and broad cross-compiler support.However, if emplace is utilized to insert elements into the colony, and no functions which involve copying or moving are utilized, T is only required to meet the requirements of Erasable.If move-insert is utilized instead of emplace, T must also meet the requirements of Move Constructible . This type is used to form the skipfield which skips over erased T elements.A growth factor of 2 tends gives the best performance in a majority of scenarios (hence why it is used for the majority of vector implementations).Colony's minimum and maximum memory block sizes can also be adjusted to suit individual use-cases.It can be reasonably compared to a "bag" or "bucket-array" styled structure, where each element location can be emptied and skipped over.
