StackAllocator

Stack-based allocator for temporary allocations.

Allocates memory linearly from a fixed buffer. All allocations can be freed at once with reset(), ideal for frame-based allocations.

Allocate memory from stack.

sizeNumber of bytes to allocate alignmentAlignment requirement in bytes (default: pointer size) Pointer to allocated memory, or nullptr if out of space

void reset()​

Reset allocator, freeing all allocations.

size_t getUsed() const​
