Struct MmapSlotArena 

pub struct MmapSlotArena { /* private fields */ }

2026-09-25: SlotArena over the peer’s mapped arena, from a raw base pointer. The peer copies between slots and its swap file; clients RDMA into and out of the same slots. The arena registers nothing; the peer registers the mapping per connection.

Implementations

impl MmapSlotArena

pub unsafe fn new(base: *mut u8, slot_bytes: usize, num_slots: usize) -> Self

2026-09-25: Wrap the mapping at base.

Safety

base must be a valid, writable mapping of >= num_slots*slot_bytes bytes that outlives this arena.
