pub struct SlotRowArena { /* private fields */ }

Arena allocator for SlotRow storage

Allocates rows from contiguous memory blocks to:

• Reduce heap fragmentation
• Improve cache locality
• Enable efficient bulk deallocation

pub fn store(&mut self, row: &SlotRow) -> SlotRowHandle

Store a SlotRow and return handle

pub fn get(&self, handle: &SlotRowHandle) -> Option<SlotRow>

Get row from handle

pub fn total_allocated(&self) -> usize

Get total allocated bytes

pub fn block_count(&self) -> usize
