hotpath-meta 0.17.0

Hotpath meta - a version of hotpath used to profile the profiler itself. Not intended for external use.
Documentation
//! 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.
//! It can provide actionable insights into time, memory, and data flow with minimal setup.
//! ## Setup & Usage
//! For a complete setup guide, examples, and advanced configuration, visit
//! [hotpath.rs](https://hotpath.rs).

// Meta crate mirrors the main crate; some code is conditionally dead
// depending on feature combinations (e.g. alloc code without global_allocator).
