1//! Opt-in hot-path instrumentation for the Rust engine.

3//! Disabled by default. Set `manabrew_engine_PERF=1` to collect counters and
4//! timings. Set `manabrew_engine_PERF_TRACE=1` to emit every increment, or
5//! `manabrew_engine_PERF_REPORT_EVERY=N` to print a summary every N continuous
6//! effect recomputations.
