# Rust profiling

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Profiling Rust performance, reducing binary size, measuring monomorphization bloat, writing Criterion benchmarks, or interpreting flamegraphs and perf output. |
| Authority | Read-only. Emits a guidance report and command transcripts to chat. No source or remote mutation. |
| Side effect | Emits a structured guidance report with profiling commands, benchmark setup, and interpretation. No source files are modified. |
| Done | A report is emitted that names the hot path, bloat source, size contributor, or benchmark result and the next action to take. |

## Inputs

1. **Target binary or benchmark** (required): the program, test, or Criterion benchmark to measure.
