Rustikon Talk - Rust Performance Profiling using hotpath-rs

This article covers a talk given at the Rustikon conference about hotpath-rs, a Rust profiler focused on performance debugging including time, memory, CPU, and async operations. It discusses the project's origin story, how it works under the hood, and includes a live instrumentation demo featuring the Zed editor. The talk marks the author's first conference presentation in over 8 years. Links to documentation, a forked Zed editor, and the samply profiler are provided.
