  "github_readme_excerpt": "# [cargo-]flamegraph\n\n[![colorized flamegraph output](example_cropped.png)](example.svg)\n\nA Rust-powered flamegraph generator with additional support for\nCargo projects! It can be used to profile anything,\nnot just Rust projects! No perl or pipes required \u003c3\n\nBuilt on top of [@jonhoo\u0027s](https://github.com/jonhoo) wonderful [Inferno](https://github.com/jonhoo/inferno) all-rust flamegraph generation library!\n\n\u003e [!TIP]\n\u003e You might want to also try [samply](https://github.com/mstange/samply), which provides a more interactive UI\n\u003e using a seamless integration with Firefox\u0027s Profiler web UI. It is also written in Rust and has better macOS support.\n\n## Quick Start\n\nInstall it, and run\n\n```bash\n# Rust projects\ncargo flamegraph\n\n# Arbitrary binaries\nflamegraph -- /path/to/binary\n```\n\nHow to use flamegraphs: [what\u0027s a flamegraph, and how can I use it to guide systems performance work?](#systems-performance-work-guided-by-flamegraphs)\n\n## Installation\n\n\\[cargo-\\]flamegraph supports\n\n- [Linux](#linux): relies on `perf`\n- [MacOS](#macos): relies on `xctrace`\n- [Windows](#windows): native support with the [blondie](https://github.com/nico-abram/blondie) library; also works with `dtrace` on Windows\n\n`cargo install flamegraph` will make the `flamegraph` and `cargo-flamegraph` binaries available in\nyour cargo binary directory. On most systems this is something like `~/.cargo/bin`.\n\n## Linux\n\n**Note**: If you\u0027re using lld (which is the default since Rust 1.90.0) or mold on Linux, you must use the `--no-rosegment` flag. Otherwise perf will not be able to generate accurate stack traces ([explanation](https://crbug.com/919499#c16)).\n\nFor example, Rust 1.90.0 and later:\n\n```toml\n[target.x86_64-unknown-linux-gnu]\nrustflags = [\"-Clink-arg=-Wl,--no-rosegment\"]\n```\n\nfor explicitly configured lld on older toolchains:\n\n```toml\n[target.x86_64-unknown-linux-gnu]\nlinker = \"/usr/bin/clang\"\nrustflags = [\"-Clink-arg=-fuse-ld=lld\", \"-Clink-arg=-Wl,--no-rosegment\"]\n```\n\nand for mold:\n\n```toml\n[target",
