1//! hotpath-rs is a simple async Rust profiler. It instruments functions, channels, futures, and streams to quickly find bottlenecks and focus optimizations where they matter most.
2//! It can provide actionable insights into time, memory, and data flow with minimal setup.
3//! ## Setup & Usage
4//! For a complete setup guide, examples, and advanced configuration, visit
5//! [hotpath.rs](https://hotpath.rs).
