Crate pprof

pprof-rs is an integrated profiler for rust program.

This crate provides a programable interface to start/stop/report a profiler dynamically. With the help of this crate, you can easily integrate a profiler into your rust program in a modern, convenient way.

A sample usage is:

let guard = pprof::ProfilerGuard::new(100).unwrap();

Then you can read report from the guard:

if let Ok(report) = guard.report().build() {
   println!("report: {}", &report);
};
