Struct InMemoryIdempotencyIndex 

pub struct InMemoryIdempotencyIndex { /* private fields */ }

In-memory IdempotencyIndex — HashMap-backed. Suitable for tests and Tier-0 dev; the PG-backed production implementation lands alongside the L2 service layer.

Implementations

impl InMemoryIdempotencyIndex

pub fn new() -> Self

Construct an empty store.

pub fn insert( &mut self, key: [u8; 16], entity: EntityId, tick: Tick, ) -> Result<(), DedupError>

Insert a new (key, entity, tick) binding. Rejects with DedupError::Conflict if the key is already bound to a different (entity, tick) pair. Idempotent re-insert of the same binding is a no-op success.

pub fn len(&self) -> usize

Number of keys currently held.

pub fn is_empty(&self) -> bool

true iff no keys are held.

Trait Implementations

impl Debug for InMemoryIdempotencyIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryIdempotencyIndex

fn default() -> InMemoryIdempotencyIndex

Returns the “default value” for a type.

impl IdempotencyIndex for InMemoryIdempotencyIndex

fn lookup(&self, key: &[u8; 16]) -> Option<(EntityId, Tick)>

Look up a prior assignment of key. None indicates the key is unused (callers may then insert).
