## What it is
pprof-rs is a CPU profiler library for Rust programs, built on top of backtrace-rs. It samples running threads and produces stack-trace reports that can be rendered as flamegraphs or exported in pprof-compatible formats.

## Use cases
- profile cpu usage of a rust program
- find hot functions in my rust application
- generate flamegraphs from rust code
- sample stack traces while my service runs
- export profiling data in pprof format
- diagnose performance bottlenecks in rust

## When to choose
- you need in-process CPU profiling for a Rust application
- you want flamegraph or pprof-format output from Rust code
- you want profiling integrated programmatically via a guard API

## When to avoid
- you need whole-system or multi-process profiling
- you are profiling non-Rust languages
- you need heap/memory profiling rather than CPU sampling

## Facets
- artifact type: library
- maturity: active
- function: monitoring, developer-tools, benchmarking
- domain: developer-tools, performance
- platform: rust
- tags: cpu-profiling, profiler, pprof-format, flamegraph, backtrace, sampling-profiler, linux, macos
