Rust Profiling

Purpose

Guide agents through Rust performance profiling: flamegraphs via cargo-flamegraph, binary size analysis, monomorphization bloat measurement, Criterion microbenchmarks, and interpreting profiling results with inlined Rust frames.

Triggers

• "How do I generate a flamegraph for a Rust program?"
• "My Rust binary is huge — how do I find what's causing it?"
• "How do I write Criterion benchmarks?"
• "How do I measure monomorphization bloat?"
• "Rust performance is worse than expected — how do I profile it?"
• "How do I use perf with Rust?"

Workflow

1. Build for profiling
