Order processing pipelines in quantitative finance often allocate scratch buffers for tasks like packet decoding, tick normalization, and position delta computation. These temporary resources must be reliably released, even when control flow branches unexpectedly or exceptions propagate. The RAII (Resource Acquisition Is Initialization) scope-guard pattern provides a robust mechanism to encapsulate arbitrary cleanup logic within a destructor, ensuring resources are freed at scope exit without er
