Expand description

SHM-backed lane implementations (attach/open only).

The backings layer is responsible for safely attaching to shared-memory layouts and exposing IO-free kernel traits.

Structs§

AttachOptions: Backing attach options.
CursorBarrier: Cursor barrier (published sequences).
GatingBarrier: Gating barrier observing a particular consumer/stage’s sequence.
ShmEventsChainRegion: Shared EventsChainLayout4 mapping that can be split into multiple queues.
ShmEventsMpscRx: SHM-backed events-chain RX lane (MPSC) over EventsChainLayout4.
ShmEventsMpscTx: SHM-backed events-chain TX lane (MPSC) over EventsChainLayout4.
ShmEventsRx: SHM-backed events-chain RX lane over EventsChainLayout4.
ShmEventsTx: SHM-backed events-chain TX lane over EventsChainLayout4.
ShmFanoutRouter: SHM-backed fanout router.
ShmFanoutRx: SHM-backed fanout RX lane.
ShmFanoutTx: SHM-backed fanout TX lane.
ShmJournalPublisher: SHM-backed journal publisher.
ShmJournalSubscriber: SHM-backed journal subscriber.
ShmSequencedSlots: A shared handle to a mapped SequencedSlotsLayout4 region.
ShmSequencedSlotsProducer: Single-producer handle over SequencedSlotsLayout4.
ShmSequencedSlotsStage: Stage that processes entries in-place and advances its gating sequence.
ShmSequencedSlotsSubscriber: Subscriber/consumer that reads from the cursor and advances a specific gating sequence.
SingleRingSnapshot: Minimal observability snapshot for SingleRing / sequenced-slots.

attach_events_mpsc_rx: Attach to an EventsChain RX lane backed by an MPSC queue (queue opts.queue, default 0).
attach_events_mpsc_tx: Attach to an EventsChain TX lane backed by an MPSC queue (queue opts.queue, default 0).
attach_events_rx: Attach to an EventsChain RX lane (queue opts.queue, default 0).
attach_events_tx: Attach to an EventsChain TX lane (queue opts.queue, default 0).
attach_fanout_router: Attach to a fanout router.
attach_fanout_rx: Attach to a fanout RX lane for consumer opts.queue.
attach_fanout_tx: Attach to a fanout TX lane.
attach_journal_publisher: Attach to a journal publisher.
attach_journal_subscriber_from: Attach to a journal subscriber starting at an explicit position.
attach_journal_subscriber_tail: Attach to a journal subscriber starting at the current tail (safe-by-default).
attach_sequenced_slots_region: Attach to a SequencedSlots region.
attach_single_ring: Attach to a SingleRing backing.
