Struct IdempotencyCtx 

pub struct IdempotencyCtx {
    pub header: String,
    pub stored_body_sha256: String,
}

Idempotency context for a case where an Idempotency-Key is in play.

Real APIs (Stripe, many fintech providers) store the SHA-256 of the body that arrived under a given key. A retry with the same key but a different body is rejected. The idempotency_collision rule recomputes the digest of the current request body and compares.

Fields

header: String

Name of the idempotency-key header (e.g., "idempotency-key").

stored_body_sha256: String

Hex-encoded SHA-256 of the body the server originally stored under this idempotency key. Must be exactly 64 hex characters.
