OxCaml introduces a [@zero_alloc] annotation that enforces zero heap allocation at compile time, preventing regressions in performance-critical code paths. This approach shifts the burden from runtime profiling to static compiler verification, offering a robust alternative to conventional optimization workflows.
Background
Jane Street has developed OxCaml, a superset of OCaml designed for high-performance financial trading systems where predictable memory behavior is crucial. The tool addresses the common challenge of allocation regressions in hot paths by leveraging compile-time assertions rather than relying solely on profilers.
