I’ve been maintaining the Rust flamegraph implementation for three years, releasing about every 3 months on average. Consider sponsoring my work if it’s been valuable to you(r team).
Cargo flamegraph's new version uses Xcode's tracer under the hood, so flamegraphing your rust code no longer requires sudo (which then messes up permissions on your build artifacts). It's a small thing but it's made flamegraphing my Rust code on MacOS so much more pleasant.
