Expand description

Shared events region (SPSC + MPSC) base layout.

Fields§

§header: LayoutHeader

Common region header (magic/version/capabilities/layout size).

§initialized: IndexbusAtomicU32

0 = uninitialized, 1 = initializing, 2 = initialized

§pad0: u32

Padding (reserved).

§pad_to_64: [u8; 40]

Pad to 64 so SlotPoolLayout (align 64) starts at offset 64.

§slot_pool: SlotPoolLayout

Slot pool backing both the SPSC and MPSC queues.

§queue: IndexQueue

SPSC queue of slot indices.

§mpsc_queue: MpscQueue

MPSC queue of slot indices.

Implementations§

impl SharedLayout

pub const REQUIRED_CAPS: u32 = caps::INDEXBUS_CAP_SUPPORTS_EVENTS

Capabilities required for this region to be considered compatible.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error
