Struct IdempotencyKey

pub struct IdempotencyKey(/* private fields */);

An opaque key the SDK attaches via the Idempotency-Key header. Reused across all retry attempts of the same logical call — that’s how the server’s 24h dedup window discriminates “this is a retry” from “this is a new request.”

Implementations

impl IdempotencyKey

pub fn new() -> Self

pub fn as_str(&self) -> &str

pub fn for_receipt(store: &str, receipt: &str) -> Self

Deterministic key for a receipt POST, derived from the store + receipt token. All posts of the same transaction (first send, reconcile re-post, StoreKit re-delivery) share one key, so the server replays its cached response within the 24h window instead of re-verifying with the store.
