About:
cargo-flamegraph is a Cargo subcommand that simplifies the process of generating flamegraphs for Rust applications. It automates the invocation of performance profilers like perf or DTrace and the subsequent processing to create visual call-graphs. This tool helps developers quickly identify performance bottlenecks and optimize their code.
Key Features:
  • Automated profiling workflow via Cargo integration
  • Supports Linux perf and macOS DTrace
  • Generates interactive SVG flamegraphs
  • Works with Rust and non-Rust binaries
Use Cases:
  • Identifying hot code paths in Rust applications
  • Comparing performance before and after code changes
  • Debugging latency issues in production services
Alternatives:
  • cargo-profiler – cargo-profiler focuses on numeric metrics, while flamegraph provides visual call graphs.
  • perf – perf is a lower-level Linux profiler requiring manual setup, whereas cargo-flamegraph automates the process.
