Struct FlatReader 

Source 
pub struct FlatReader<T: FlatStruct> { /* private fields */ }
Expand description

Liest FlatStruct-Samples direkt aus SHM-Slots.

Implementations§

Source§

impl<T: FlatStruct> FlatReader<T>

Source

pub fn new(alloc: Arc<InMemorySlotAllocator>, reader_index: u8) -> Self

Erzeugt einen Reader ueber einem Allocator.

Source

pub fn type_hash(&self) -> [u8; 16]

Liefert Type-Hash — fuer Discovery-Match.

Source

pub fn read(&self) -> Result<Option<T>, SlotError>

Spec §9.1 read_flat. Liefert das neueste ungelesene Sample. Setzt automatisch das reader-Bit im reader_mask.

Spec §6.1 Type-Hash-Cross-Validation: vor dem Slot-Read wird T::TYPE_HASH gegen den am SlotBackend hinterlegten Hash geprueft. Bei Mismatch: keine Slots werden dereferenziert, Err(SlotError::SampleTooLarge) mit Schema-Drift-Indikation.

§Errors
  • SampleTooLarge bei TYPE_HASH-Mismatch (Spec §6.1).
  • Wire-/Layout-Fehler oder Slot-Lock-Poison wie sonst.
