Module: Mongo::Error::OperationFailure::Family

Extended by:
Forwardable
Includes:
ReadWriteRetryable, SdamErrorDetection
Included in:
Mongo::Error::OperationFailure, ServerTimeoutError
Defined in:
lib/mongo/error/operation_failure.rb

Overview

Implements the behavior for an OperationFailure error. Other errors (e.g. ServerTimeoutError) may also implement this, so that they may be recognized and treated as OperationFailure errors.
