pub fn execute_explain(
rs: &RuleSet,
ctx: &ExecCtx<'_>,
input: &str,
) -> Result<(String, ExplainTrace)>Expand description
Like execute but records per-op stats. Only top-level ops are
recorded — macros and split sub-chains run silently. Adds ~µs of
overhead per op for line/byte counting; safe for interactive use,
avoid in tight loops.
