Crate pprof[−][src]
Expand description
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);
};
