Struct ShmEventsChainRegion 

pub struct ShmEventsChainRegion { /* private fields */ }

Shared EventsChainLayout4 mapping that can be split into multiple queues.

Slot forwarding APIs (try_recv_slot / publish_slot) require that all participating producers/consumers share the same mmap, because the slot handle contains raw pointers into the mapping.

Implementations

impl ShmEventsChainRegion

pub fn open(opts: &AttachOptions, lane: &str) -> Result<Self, BackingError>

Open (or create) an EventsChainLayout4 mapping.

pub fn queue_spsc( &self, idx: usize, ) -> Result<(ShmEventsTx, ShmEventsRx), BackingError>

Split SPSC queue idx into (tx, rx) lanes that share this mapping.

pub fn queue_mpsc( &self, idx: usize, ) -> Result<(ShmEventsMpscTx, ShmEventsMpscRx), BackingError>

Split MPSC queue idx into (tx, rx) lanes that share this mapping.
