Defined in:

Overview

Contains logic to handle idempotency checks.

Idempotency checks are used to skip operation execution in certain conditions.

An idempotency check returns a Result monad. If it returns a Failure, the operation body is skipped but the operation is considered successful. The value or failure will be merged to the result context in order to enrich it (the failure should contain something that operation body would return normally to mimic a proper operation call result).

Component logs the failed check with ‘error_reporter`.
