It’s just a variation of arena allocation. You allocate everything for the current frame in an arena. When the frame is complete. You free the entire arena, without needing any heap walking.

A generational GC achieves a similar end result, but has to heuristically discover the generations, whereas an arena allocator achieves the same result deterministically And without extra heap walking.

Linear or stack allocator are other common terms. Just a memory arena where an allocation is just a pointer bump and you free the whole buffer at once by returning the pointer to the start of the arena.
