WebNov 8, 2011 · This allocator uses a user-provided fixed-size buffer as an initial source of memory, and then falls back on a secondary allocator ( std::allocator by default) when it runs out of space. Things to consider: Before you just go ahead and use a stack allocator, you need to consider your allocation patterns.

Fast Efficient Fixed-Size Memory Pool: No Loops and No Overhead
Fixed-size blocks allocation, also called memory pool allocation, uses a free list of fixed-size blocks of memory (often all of the same size). This works well for simple embedded systems where no large objects need to be allocated, but suffers from fragmentation , especially with long memory addresses.

The task of fulfilling an allocation request consists of locating a block of unused memory of sufficient size. Memory requests are satisfied by allocating portions from a large pool of memory called the heap or free store. At any given time, some parts of the heap are in use, while some are "free" (unused) and thus available for future allocations. WebJul 19, 2024 · Seems your allocator in the end will only be able to allocate memory for POD's and will not actually construct objects (I think that's what @GoswinvonBrederlow is also trying to tell you). – Pepijn Kramer Jul 19, 2024 at 15:19 constructing object is not an allocator's duty, it is std::construct_at 's duty.
