Struct IdempotencyLog 

pub struct IdempotencyLog { /* private fields */ }

R1 durable single-assignment outcomes. Every proposal/commit outcome is written once and never reassigned; redelivery of the same idempotency key with equivalent content returns the prior result, and key reuse for different content is invalid.

Implementations

impl IdempotencyLog

pub fn new() -> Self

Record an outcome under an idempotency key. On first write, stores and returns the outcome. On redelivery with equivalent content, returns the prior outcome. On key reuse with different content, returns an error.
